Annihilation by Jeff VanderMeer

Something is wrong in Area X, an isolated coastal region, full of wildlife, empty of human inhabitants. The Southern Reach, as the organization responsible for exploring, explaining, and possibly containing Area X, has sent a team of scientists through the border to investigate. This the twelfth expedition. The previous expeditions were not successful. Successful at what? That's a good question. Something wrong in Area X? It might be that Area X is pure wrongness, or it could just be a matter of point of view. This is a deeply unsettling novel about ecosystems and estrangement, which explores the idea that all of nature is full of monsters if looked at closely enough. (The first of a trilogy; the others are coming out this Spring and Fall.)
