Speculative Fiction

David Brin

The creative exercise in this book is the cheap and easy creation of human 'dittos', copies of one's mind complete with a body, albiet one that only lasts 24 hours.  Once the life of a ditto is nearly over, its creator can inload its memories, effectively allowing people to experience multiple lifespans.  Even the poorest people can create at least one ditto a day to earn a wage as an unskilled laborer.  Others do more interesting things with their copies, anything from selling them as specialized courteseans, to experiencing thrills much too risky for a real body, to creating a team of hyper-focused detectives.

The latter is the MO of Albert Morris, whose various selves independently stumble onto some disturbing happenings that seem to be unrelated at first - but when the creator of the primary dittoing technology, his chief scientist, and the scientist's daughter are all involved, things get interesting quickly.

Like Brin's other works, Kiln People starts at a reasonably fast pace and maintains it for the entirety of the story.  This is especially impressive since his four first-person points of view are of Albert and his three dittos, and the entire book only spans a handful of days.  The book is also nice and long, the paperback weighs in at a meaty 567 pages.  Brin continually delights with little details of how dittotech has impacted society, though his prose is nothing special and I was not particularly attached to any of the characters.  All in all, a good solid speculative work of science fiction.
Across known space, Humanity is a rare example of a species that achieved sentience and a starfaring civilization without the evident help of a Patron race.  In the eyes of some aliens, this makes them unique; in others, it makes them outcasts.  Humans have earned themselves a tenuous status in Galactic society, however, as they had already Uplifted two other races - chimpanzees and dolphins - by the time of First Contact.

With the gift of alien technology, Humans are exploring the environs of Sol itself.  Drawn into the Sundiver project by an alien friend, the scientist Jacob Demwa soon finds that the sun may harbor the secret behind Humanity's apparent lack of Patronage.  But strange behavior from everyone involved - Earth natives and aliens both - puts the entire project at risk, and Jacob has the opportunity to sort things out - if he can get his own fractured mind to cooperate with him.

Sundiver is a lovely mixture of the hard sci-fi and mystery genres.  The writing is solid, if rarely evocative, and the primary character is lovingly fleshed out.  Secondary characters lack depth but work fine as they are.

The creative exercise of the setting - chains of Patron and Client races, each with their own (sometimes hidden) agendas, flowing around the 'orphaned' Human race, the latter still struggling with social issues on a grand scale, opens up lots of possibility for future works.  The mystery element will keep even the sharpest of readers guessing.  Combined with hard sci-fi, this book was a very enjoyable, relatively quick read.  Fortunately, Brin has seen fit to grant us several more titles set in this universe.
Startide Rising picks up about 200 years after Sundiver left off.  The first mostly-dolphin starship crew is assembled and sent on a survey mission.  Uopn finding a huge derelict fleet of unknown origin and sending a message home about it, several hostile races hound the small survey craft until she crashes in the ocean of a metal-rich waterworld.

Apparently, the hostiles are all quasi-fanatacial races who believe in the eventual return of the Progenitors, the race or races who began the practice of Uplift.  It soon becomes clear that the fanatics think the derelict fleet is a sign pertaining to the Progenitors, and they want the location of that fleet badly.

The Earthlings struggle to repair their ship and escape before the hostiles find them, but the untried crew must first face internal treachery as well as the mysterious hazards of the planet.  They also encounter a number of oddities with the Library, the supposed sum total of all sentient knowledge, that was made available to Earth races by the Galactic civilization.

The overarcing plot of Startide Rising is fairly straightforward; it's the subtleties of the crew's struggles that make up the meat of the story.  Brin continues with his engaging writing, and the closing sequence of the books is composed of wonderfully concerted episodes of action that make for a rousing finish.  Brin spreads out his character development this time, so we have many more points of view to consider.
The Postman has a rugged post-apocalyptic setting based on a post-nuclear-war USA that almost - but not quite - survived total collapse.  Gordon, a loner who trades old tales of prewar culture in bardic style for his meals, meanders about from village to village, looking for someone who is trying to build something more than a subsistence society.

Falling into misfortune, Gordon uses the uniform of a long-dead postal worker to weave an elaborate lie that will enable him to survive.  Unwittingly, the false postman becomes a source of hope to the small, isolated communities that have had no inkling that the nation ever survived.  That tremulous hope has its own war to survive before it can really take root, though.

The writing of Postman is average, and the pacing rather compact.  I think Brin could've fleshed it out more without losing the point of the story.  Most of what Brinn does in a little over 300 pages (paperback) is make interesting psychological and sociological speculations.  We get snapshots of half a dozen communities, each with its own form of government; each of which is permanently changed in Gordon's wake.  The latter is what sets this book apart from the few other post-apocalyptic works I've read.  It is a light snack of brain food, and I wish it had been more.
