The Uplift War
Brin's Hugo and Locus Award-winning third Uplift novel drops readers into a guerilla war on a colony world occupied by alien invaders who want to exploit humanity's ethically fraught practice of uplifting chimpanzees to sentience. The chimp-human resistance is both action-packed and genuinely thought-provoking on questions of consent, autonomy, and what it means to bring another species into sapience without their agreement. The galactic civilization backdrop is one of science fiction's more imaginative constructs. A clear caveat: the book contains explicit sexual content and graphic violence, placing it firmly in adult territory. It also works best with familiarity with the earlier Uplift books. For adult SF readers ready for those conditions, this is award-caliber work.
