... it is reasonable to hope
that in the not too distant future
we shall be competent to understand
so simple a thing as a star.
A. S. Eddington, 1926
In all the universe, no species has ever reached for the stars without the guidance of a patron — except perhaps mankind. Did some mysterious race begin the uplift of humanity aeons ago? And if so, why did they abandon us?
Under the caverns of Mercury, Expedition Sundiver prepares for the most momentous voyage in our history, a journey into the boiling inferno of the sun... to seek our destiny in the cosmic order of life.
Sundiver (The Uplift Saga, Book 1), is the first book in the Uplift series — and also David Brin's first published novel.
The uplift series of novels and short stories is set in a future universe in which no species can reach sentience without being "uplifted" (genetically brought to sapience) by a patron race, which then "owns" the uplifted species for 100,000 years. But the greatest mystery of all remains unsolved: who uplifted humankind? Earth has no known link to the Progenitors — and that terrifies client and patron species alike. Should its inhabitants be allowed to exist?

Sundiver has been translated into Bulgarian, Chinese, French, German, Italian, Polish, Romanian, Russian, and Spanish. Here are some of the covers of the foreign and foreign-language publications.
"The central concept in Sundiver is an interesting and clever one: all intelligent races in the galaxy have been uplifted to sentience by a parent race, although humanity is the exception to this as it appears they haven't. What they have done though is uplift two of Earth's other animals to sentience, the Dolphin and Chimpanzee, and in doing so have become a parent race themselves. With this done before they were discovered by the other races of the galaxy, humanity have been given a status that some within the galactic society believe they are not worthy of."
"... I dig it because I'm into books on animal intelligence, transhuman SF, etc... and it's a great spin on the evolution/creation debate. Sundiver is actually a murder mystery... complete with a 'parlor reveal' scene. There also is an interesting political argument about psychological profiling, surveillance and citizenship (if we can prove some people are biologically/psychological sociopath/violent/whatever... what do we do about it, if we can't fix them?)"
"David Brin writes science fiction the way it should be written — with imagination, heroic characters, and the triumph of all that is good in the human spirit. Sundiver is a prime example of how good Brin's books can be."
"Brin has done a superb job on all counts."
"Brin has a fertile and well-developed imagination ... coupled with a sinuous and rapid-paced style."
David Brin's science fiction novels have been New York Times Bestsellers, winning multiple Hugo, Nebula and other awards. At least a dozen have been translated into more than twenty languages. They range from bold and prophetic explorations of our near-future to Brin's Uplift series, envisioning galactic issues of sapience and destiny (and star-faring dolphins!). Learn More
Short stories and novellas have different rhythms and artistic flavor, and Brin's short stories and novellas, several of which earned Hugo and other awards, exploit that difference to explore a wider range of real and vividly speculative ideas. Many have been selected for anthologies and reprints, and most have been published in anthology form. Learn More
Since 2004, David Brin has maintained a blog about science, technology, science fiction, books, and the future — themes his science fiction and nonfiction writings continue to explore. Learn More
Who could've predicted that social media — indeed, all of our online society — would play such an important role in the 21st Century — restoring the voices of advisors and influencers! Lively and intelligent comments spill over onto Brin's social media pages. Learn More
David Brin's Ph.D in Physics from the University of California at San Diego (the lab of nobelist Hannes Alfven) followed a masters in optics and an undergraduate degree in astrophysics from Caltech. Every science show that depicts a comet now portrays the model developed in Brin's PhD research. Learn More
Brin's non-fiction book, The Transparent Society: Will Technology Force Us to Choose Between Freedom and Privacy?, continues to receive acclaim for its accuracy in predicting 21st Century concerns about online security, secrecy, accountability and privacy. Learn More
Brin speaks plausibly and entertainingly about trends in technology and society to audiences willing to confront the challenges that our rambunctious civilization will face in the decades ahead. He also talks about the field of science fiction, especially in relation to his own novels and stories. To date he has presented at more than 200 meetings, conferences, corporate retreats and other gatherings.Learn More
Brin advises corporations and governmental and private defense- and security-related agencies about information-age issues, scientific trends, future social and political trends, and education. Urban Developer Magazine named him one of four World's Best Futurists, and he was appraised as "#1 influencer" in Onalytica's Top 100 report of Artificial Intelligence influencers, brands & publications.

reviews and recommendations
"Otherness is a multi-faceted book with a surplus of ideas. Intelligent and impassioned SF constructed with a quality control to rival that of NASA."
"I would consider Existence to be a triumphant, epic Science Fiction novel on many levels. It stayed with me after I set it aside for the day, continues to simmer in my mind now that I've finished reading it, and has opened up a gateway to Brin's novels I'd wanted to enter for a while. Brin achieved an excellent gestalt of character, big ideas, and narrative energy."
"Brin expounds upon his belief that people need to keep watch on snooping governments, employers, insurance companies, and so on.... In assessing the current state of affairs, Brin divulges a barrage of ways and means of monitoring electronic transmissions."
"Like E E "Doc" Smith before him, Brin gives joy and imparts a Sense of Wonder; but he also thinks about the near world."

— A. S. Eddington, 1926
"Makakai, are you ready?"
Jacob ignored the tiny whirrings of motors and valves in his metal cocoon. He lay still. The water lapped gently against the bulbous nose of his mechanical whale, as he waited for an answer.
One more time he checked the tiny indicators on his helmet display. Yes, the radio was working. The occupant of the other waldo whale, lying half submerged a few meters away, had heard every word.
The water was exceptionally clear today. Facing downward, he could see a small leopard shark swim lazily past, a bit out of place here in the deeper water offshore.
"Makakai... are you ready?"
He tried not to sound impatient, or betray the tension he felt building in the back of his neck as he waited. He closed his eyes and made the delinquent muscles relax, one by one. Still, he waited for his pupil to speak.
"Yesss... let'sss do it!" came the warbling, squeaky voice, at last. The words sounded breathless, as if spoken grudgingly, in lieu of inhalation.
A nice long speech for Makakai. He could see the young dolphin's training machine next to his, its image reflected in the mirrors that reflected his faceplate. Its gray metal flukes lifted and fell slightly with the swell. Feebly, without their power, her artificial fins moved, sluggishly under the transient, serrated surface of the water.
She's as ready as she'll ever be, he thought. If technology can wean a dolphin of the Whale-Dream, now's the time we'll find out.
He chinned the microphone switch again. "All right, Makakai. You know how the waldo works. I will amplify any action you make, but if you want the rockets to cut in, you'll have to give the command in English. Just to be fair, I have to whistle in trinary to make mine work."
"Yesss!" she hissed. Her waldo's gray flukes thrashed up once and down with a boom and a spray of saltwater.
With a half muttered prayer to the Dreamer, he touched a switch releasing the amplifiers on both Makakai's waldo and his own, then cautiously turned his arms to set the fins into motion. He flexed his legs, the massive flukes thrust back jerkily in response, and his machine immediately rolled over and sank.
Jacob tried to correct but overcompensated, making the waldo tumble even worse. The beating of his fins momentarily made the area around him a churning mass of bubbles, until patiently, by trial and error, he got himself righted.
He pushed off again, carefully, to get some headway, then arched his back and kicked out. The waldo responded with a great tail-slashing leap into the air.
The dolphin was almost a kilometer off. As he reached the top of his arc, Jacob saw her fall gracefully from a height of ten meters to slice smoothly into the swell below.
He pointed his helmet beak at the water and the sea came at him like a green wall. The impact made his helmet ring as he tore through tendrils of floating kelp, sending a golden Garibaldi darting away in panic as he drove downwards.
He was going in too steep. He swore and kicked twice to straighten out. The machine's massive metal flukes beat at the water to the rhythmic push of his feet, each beat sending a tremor up his spine, pressing him against the suit's heavy padding. When the time was right, he arched and kicked again. The machine ripped out of the water.
Sunlight flashed like a missile in his left window, its glare drowning the dim glow of his tiny instrument panel. The helmet computer chuckled softly as he twisted, beak down, to crash into the bright water once again.
As a school of tiny silver anchovies scattered before him, Jacob hooted out loud with exhilaration.
His hands slipped along the controls to the rocket verniers, and at the top of his next arc he whistled a code in trinary. Motors hummed, as the exoskeleton extended winglets along its sides. Then the boosters cut in with a savage burst, pressing the padded headpiece upward with the sudden acceleration, pinching the back of his skull as the waves swept past, just below his hurtling craft.
He came down near Makakai with a great splash. She whistled a shrill trinary welcome. Jacob let the rockets shut off automatically and resumed the purely mechanical leaping beside her.
For a time they moved in unison. With each leap Makakai grew more daring, performing twists and pirouettes during the long seconds before they struck the water. Once, in midair, she rattled off a dirty limerick in dolphin, a low piece of work, but Jacob hoped they'd recorded it back at the chase boat. He'd missed the punch line at the crashing end of the aerial cycle.
The rest of the training team followed behind them on the hovercraft. During each leap he caught sight of the large vessel, diminished, now, by distance, until his impact cut off everything but the sounds of splitting water, Makakai's sonar squeaking, and the rushing, phosphorescent blue-green past his windows.
Jacob's chronometer indicated that ten minutes had passed. He wouldn't be able to keep up with Makakai for more than a half hour, no matter how much amplification he used. A man's muscles and nervous system weren't designed for this leap-and-crash routine.
"Makakai, it's time to try the rockets. Let me know if you're ready and we'll use them on the following jump."
They both came down into the sea and he worked his flukes in the frothy water to prepare for the next leap. They jumped again.
"Makakai, I'm serious now. Are you ready?"
They sailed high together. He could see her tiny eye behind a plastic window as her waldo-machine twisted before slicing into the water. He followed an instant later.
"Okay, Makakai. If you don't answer me, we'll just have to stop right now."
Blue water swept past, along with a cloud of bubbles, as he pushed along beside his pupil.
Makakai twisted around and dove down instead of rising for another leap. She chattered something almost too fast to follow in trinary... about how he shouldn't be a spoilsport.
Jacob let his machine rise slowly to the surface. "Come dear, use the King's English. You'll need it if you ever want your children to go into space. And it's so expressive! Come on. Tell Jacob what you think of him."
There were a few seconds of silence. Then he saw something move very fast below him. It streaked upward and, just before it hit the surface, he heard Makakai's voice shrilly taunt:
"Ch-chase me, ch-chump! I fly-y-y!"
With the last word, her mechanical flukes snapped back and she leaped out of the water on a column of flame.
Laughing, he dove to give himself headway and then launched into the air after his pupil.
Gloria handed him the strip chart as soon as he finished his second cup of coffee. Jacob tried to make his eyes focus on the squiggly lines, but they swam back and forth like ocean swells. He handed the chart back.
"I'll look at the data later. Can you just give me a summary? And I'll take one of those sandwiches now, too, if you'll let me clean up."
She tossed him a tuna on rye and sat on the countertop, her hands on the edges to compensate for the swaying of the boat. As usual, she was wearing next to nothing. Pretty, well endowed, and with long black hair, the young biologist wore next to nothing very well.
"I think we have the brainwave information we need now, Jacob. I don't know how you did it, but Makakai's attention span in English was at least twice normal. Manfred thinks he's found enough associated synaptic clusters to give him a boost in his next set of experimental mutations. There are a couple of nodes that he wants to expand in the left cerebral lobe of Makakai's offspring.
"My group is happy enough with the present. Makakai's facility with the waldo-whale proves that the current generation can use machines."
Jacob sighed. "If you're hoping these results will persuade the Confederacy to cancel the next generation of mutations, don't count on it. They're running scared. They don't want to have to rely forever on poetry and music to prove that dolphins are intelligent. They want a race of analytical tool users, and giving codewords to activate a rocket waldo just won't qualify. Twenty to one Manfred gets to cut."
Gloria reddened. "Cutting! They're people, a people with a beautiful dream. We'll carve them into engineers and lose a race of poets!"
Jacob put down the crust of his sandwich. He brushed crumbs away from his chest. Already he regretted having said anything.
"I know, I know. I wish things could go a little slower, too. But look at it this way. Maybe the fins'll be able to put the Whale-Dream into words someday. We won't need trinary to discuss the weather, or Aborigine-pidgin to talk philosophy. They'll be able to join the chimps, thumbing their metaphorical noses at the Galactics while we put on an act of being dignified adults."
Jacob raised his hand to cut her off. "Can we discuss this later? I'd like to stretch out for a little while, and then go down and visit with our girl."
Gloria frowned for a moment, then smiled openly.
"I'm sorry, Jacob, you must really be tired. But at least today, finally, everything worked."
Jacob allowed himself to return her grin. On his broad face the toothy smile brought out lines around his mouth and eyes.
"Yes," he said, rising to his feet. "Today everything worked."
"Oh by the way, while you were down, there was a call for you. It was an Eatee! Johnny was so excited about it that he barely remembered to take a message. I think it's around here somewhere."
She pushed aside the lunch dishes and plucked up a slip of paper. She handed it to him.
Jacob's bushy eyebrows knotted together as he looked down at the message. His skin was taut and dark from a mixture of ancestry and exposure to sun and saltwater. The brown eyes tended to narrow to fine slits when he concentrated. He brought a callused hand to the side of his hooked, amerind nose and struggled with the radio operator's handwriting.
"I guess we all knew that you worked with Eatees," Gloria said. "But I sure didn't expect to get one on the horn out here! Especially one that looks like a giant broccoli sprout and talks like a Minister of Protocol!"
Jacob's head jerked up.
"A Kanten called? Here? Did he leave his name?"
"It should be down there. Is that what it was? A Kanten? I'm afraid I don't know my aliens that well. I'd recognize a Cynthian or a Tymbrimi, but this one was new to me."
"Um... I'm going to have to call somebody. I'll clean up the dishes later so don't you touch them! Tell Manfred and Johnny I'll be down in a little while to visit with Makakai. And thanks again." He smiled and touched her shoulder lightly, but as he turned his expression quickly relapsed to one of worried preoccupation.
He passed on through the forward hatch, clutching the message. Gloria looked after him for a moment. She picked up the data charts and wished she knew what it would take to hold the man's interest for more than an hour, or a night.
Jacob's cabin was barely a closet with a narrow fold-down bunk, but it offered enough privacy. He pulled his portable teli out of a cabinet near the door and set it on the bunk.
There was no reason to assume that Fagin had called for any other purpose than to be sociable. He had, after all, a deep interest in the work with dolphins.
There had been a few times, though, when the alien's messages had led to nothing but trouble. Jacob considered not returning the Kanten's call.
After a moment's hesitation, he punched out a code on the face of the teli and settled back to compose himself. When he came right down to it, he couldn't resist an opportunity to talk with an E.T., anywhere, anytime.
A line of binary flashed on the screen, giving the location of the portable unit he was calling. The Baja E.T. Reserve. Makes sense, Jacob thought. That's where the Library is. There was the standard warning against contact with aliens by Probationary Personalities. Jacob looked away with distaste. Bright points of static filled the space above the blankets and in front of the screen, and then Fagin stood, en-replica, a few inches away.
The E.T. did look somewhat like a giant sprout of broccoli. Rounded blue and green shoots formed symmetrical, spherical balls of growth around a gnarled, striated trunk. Here and there tiny crystalline flakes tipped a few of the branches, forming a cluster near the top around an invisible blowhole.
The foliage swayed and the crystals near the top tinkled from the passage of air the creature exhaled.
"Hello, Jacob," Fagin's voice came tinnily out of midair. "I greet you with gladness and gratitude and with the austere lack of formality upon which you so frequently and forcefully insist."
Jacob fought back a laugh. Fagin reminded him of an ancient Mandarin, as much for the fluting quality of his accent as for the convoluted protocol he used with even his closest human friends.
"I greet you, Friend-Fagin, and wish you well with all respect. And now that that's over, and before you say even a word, the answer is no."
The crystals tinkled softly. "Jacob! You are so young and yet so perspicacious! I admire your insight and ability to divine my purpose in calling you!"
Jacob shook his head.
"Neither flattery nor thickly veiled sarcasm, Fagin. I insist on speaking colloquial English with you because it's the only way I have a chance of avoiding getting screwed whenever I deal with you. And you know very well what I'm talking about!"
The alien shook, giving a parody of a shrug.
"Ah, Jacob, I must bow to your will and use the highly esteemed honesty of which your species should be so proud. It is true that there is a slight favor for which I had the temerity to ask. But now that you have given me your answer... based no doubt on certain past unpleasant occurrences, most of which nevertheless turned out for the best... I shall simply drop the subject.
"Would it be possible to inquire how your work with the proud Client species 'porpoise' proceeds?"
"Uh, yes, the work is going very well. We had a breakthrough today."
"That is excellent, I am certain that it could not have happened without your intervention. I heard that your work there was indispensable!"
Jacob shook his head to clear it. Somehow Fagin had taken the initiative again.
"Well, it's true I was able to help out early on with the Water-Sphinx problem, but since then my part hasn't been all that special. Hell, anyone could have done what I've been doing here lately."
"Oh, that is something that I find very hard to believe!"
Jacob frowned. Unfortunately, it was true. And from now on the work here at the Center for Uplift would be even more routine.
A hundred experts, some more qualified in porp-psych than he, were waiting to step in. The Center would probably keep him on, partly out of gratitude, but did be really want to stay? Much as be loved dolphins and the sea, he'd found himself more and more restless lately.
"Fagin, I'm sorry I was so rude at first. I'd like to hear what you called me about... provided you understand that the answer is still probably no."
Fagin's foliage rustled.
"I had the intention of inviting you to a small and amicable meeting with some worthy beings of diverse species, to discuss an important problem of a purely intellectual nature. The meeting will be held this Thursday, at the Visitors Center in Ensenada, at eleven o'clock. You will be committed to nothing if you attend."
Jacob chewed on the idea for a moment.
"E.T.'s, you say? Who are they? What's this meeting about?"
"Alas, Jacob, I am not at liberty to say, at least not by teli. The details will have to wait until you come, if you come, on Thursday."
Jacob immediately became suspicious. "Say, this 'problem' isn't political, is it? You're being awfully close."
The image of the alien was very still. Its verdant mass rippled slowly, as if in contemplation.
"I have never understood, Jacob," the fluting voice finally resumed, "why a man of your background takes so little interest in the interplay of emotions and needs which you call 'politics.' Were the metaphor appropriate, I would say that politics is 'in my blood.' It certainly is in yours."
"You leave my family out of this! I only want to know why it's necessary to wait until Thursday to find out what all of this is about!"
Again, the Kanten hesitated.
"There are... aspects of this matter which would best not be spoken over the ether. Several of the more thalamic of the contesting factions in your culture might misuse the knowledge if they... overheard. However, let me assure you that your part would be purely technical. It is your knowledge we wish to tap, and the skills you have been using at the Center."
Bull! Jacob thought. You want more than that.
He knew Fagin. If he attended this meeting the Kanten undoubtedly would try to use it as a wedge to get him involved in some ridiculously complicated and dangerous adventure. The alien had already done it to him on three occasions in the past.
The first two times Jacob hadn't minded. But he'd been a different sort of person then, the kind who loved that sort of thing.
Then came the Needle. The trauma in Ecuador had changed his life completely. He had no desire to go through anything like it again.
And yet, Jacob felt a powerful reluctance to disappoint the old Kanten. Fagin had never actually lied to him, and he was the only E.T. he'd met who was unabashedly an admirer of human culture and history. Physically the most alien creature he knew, Fagin was also the one extraterrestrial who tried hardest to understand Earthmen.
I should be safe if I simply tell Fagin the truth, Jacob thought. If he starts applying too much pressure I'll let him know about my mental state — the experiments with self-hypnosis and the weird results I've been getting. He won't push too hard if I appeal to his sense of fair play.
"All right." he sighed. "You win, Fagin. I'11 be there. Just don't expect me to be the star of the show."
Fagin's laughter whistled with a flavor of woodwinds. "Do not be concerned about that, Friend-Jacob! In this particular show no one will mistake you for the star!"
The Sun was still above the horizon as he walked along the upper deck toward Makakai's quarters. It loomed, dim and orange among the sparse clouds in the west — a benign, featureless orb. He stopped at the rail for a moment to appreciate the colors of the sunset and the smell of the sea.
He closed his eyes and allowed the sunlight to warm his face, the rays penetrating his skin with gentle, browning insistence. Finally, he swung both legs over the rail and dropped to the lower deck. A taut, energized feeling had almost replaced the day's exhaustion. He began to hum a fragment of a tune — out of key, of course.
A tired dolphin drifted to the edge of the pool when he arrived. Makakai greeted him with a trinary poem too quick to catch, but it sounded amiably nasty. Something about his sex life. Dolphins had been telling humans dirty jokes for thousands of years before men finally started breeding them for brains and for speech, and began to understand. Makakai might be a lot smarter than her ancestors, Jacob thought, but her sense of humor was strictly dolphin.
"Well," he said. "Guess who's had a busy day."
She splashed at him, more weakly than usual, and said something that sounded a lot like "Br-r-a-a-a-p you!"
But she moved in closer when he hunkered down to pat his hand into the water and say hello.
