A much tougher read than Annihilation. You only really understand the scope of what's happening in the last 50 pages or so. Up until then, you're wading through bureaucracy and childhood trauma with only the occasional glimpse into something more sinister. I think it works? The character's quite twisted-up inside and his defenses are always up, so it makes sense that the story would be so dense. But I can't be sure. It warrants re-reading.
