Absolutely loved Annihilation. I expected Roadside Picnic, but got Lovecraftian incomprehensible horrors, government conspiracies, and main character coming to terms with themselves and events in their life.

Authority is a bit different, but the feeling of dread and being lost is still present throughout the book.

This book made me feel so much dread that I couldn't even finish it.

An overall solid series. I read Absolution last year and am about to start his Ambergris series as soon as my library hold comes in.
