I have to admit. I'm a little relieved to be done with this series. Wherever I would walk while reading either this book or its predecessor, Startide Rising, people would inevitably look at the cover, glance away quickly, then slowly look back, eyes questioning. "Is that...?" "Yes," I would answer, "those are chimpanzees. Yes, they're in space. No, I am not reading this on a dare." At the end of the day, regardless of how many awards this series has won (oodles), or how detailed and complex the universe that Brin has created, there is going to be a good chunk of the reading world that will write off the Uplift trilogy the moment they hear the words "chimps in space."
Which is a real shame because this series has one of the best premises in all of science fiction, namely that intelligent life never arises naturally in the universe but is part of a millennia long tradition known as Uplift, in which sapient species are indentured to their patrons for a hundred thousand years before being granted their own freedom to determine their genetic direction. In Startide Rising, Brin focused on one of two species that humans had uplifted, the dolphins, who had stumbled across a derelict fleet that may or may not belong to the long-fabled Progenitors, the species that had set the template for Uplift throughout the galaxy, and sparked a religious war throughout the galaxy.
The Uplift War is set immediately after the events of Startide Rising and focuses on humankind's second client species, the chimpanzees of the human colony world of Garth, a small backwater planet far removed from the conflict tearing the galaxy apart until a race of giant birds known as the Gubru decide to conquer Garth and hold it hostage until Earth decides to share their discovery. Unbeknownst to the Gubru though, humans have not been resting on their laurels after uplifting dolphins and chimps and are involved in a highly illegal gambit to uplift Earth's very own gorillas without incurring the wrath of the galaxy. Caught up in this conflict are the human son of the planet's governor, Robert Oneagle, the mildly telepathic daughter of a Tymbrimi diplomat, Athaclena, and Fiben Bolger, a chimpanzee from the Garth militia, who all find themselves running a ragtag guerilla war (oh trust me, that pun is used widely throughout the book) against the space chickens after the standard military forces are captured and held hostage.
As always it is Brin's eye for detail that makes this book fairly hum with energy. The meticulousness of detail afforded to the Gubru mating dance/policy summit, the Uplift tests that the chimpanzees must master in order to prove that they are actually sapient creatures in the eyes of galactic society, the telepathic bonds shared between father and daughter Tymbrimi- all are so well thought out and detailed that, despite how outlandish the plot description may be, I never once found myself rolling my eyes or doubting the internal logic of the book's world. Brin even addressed my main complaint from Startide Rising and doesn't resort to resolving conflicts out of scene but describes the resolution in very satisfying detail.
This is an amazingly satisfying series that I would recommend to anyone who enjoys thinking about the strange course that adaptation and evolution often take or who enjoy tales set in a fully-rendered universe. I just learned that there is a follow-up trilogy after this one that addresses what happens to the crew of the Streaker from Startide Rising and I know that I will be dipping into them over the rainy months ahead.
