Authority (The Southern Reach Trilogy)

For thirty years, a secret agency called the Southern Reach has monitored expeditions into Area X, a remote and lush terrain mysteriously sequestered from civilization. After the twelfth expedition, the Southern Reach is in disarray, and John Rodriguez is the team's newly appointed head. From a series of interrogations, a cache of hidden notes, and more than two hundred hours of profoundly troubling video footage, the secrets of Area X begin to reveal themselves.
