Acceptance | Jeff VanderMeer

It is winter in Area X, the mysterious wilderness that has defied explanation for thirty years, rebuffing expedition after expedition, refusing to reveal its secrets. As Area X expands, the agency tasked with investigating and overseeing it--the Southern Reach--has collapsed on itself in confusion. Now one last, desperate team crosses the border, determined to reach a remote island that may hold the answers they've been seeking. If they fail, the outer world is in peril. 

Meanwhile, Acceptance tunnels ever deeper into the circumstances surrounding the creation of Area X--what initiated this unnatural upheaval? Among the many who have tried, who has gotten close to understanding Area X--and who may have been corrupted by it?
