The Southern Reach Series Tome 4
Absolution

Decades before Area X was formed, a science expedition meets a mysterious end on the Forgotten Coast and the surrounding land is marked as a high-priority area of interest for Central, the shadowy government agency responsible for monitoring extraordinary threats. Charged with investigating is Old Jim, a washed-up Central operative thrust back into the field. He quickly uncovers a long and troubling record of government agents meddling with forces they clearly cannot comprehend and a landscape that, one way or another, seems to consume all who enter it.
Sweeping in scope and ever-terrifying, Absolution is the final word on Jeff VanderMeer's Southern Reach Series, one of the most provocative and popular speculative fiction series of our time.
