Acceptance was a viscerally rich and enjoyable book to read (for those who enjoy feeling confused and paranoid) and a fitting ending to the trilogy, but this book wasn't as gripping to me as Annihilation was. The four different points of view got a lot done, story-wise, in a relatively short period of time, but I found the device made the book a little choppy. And while the first two books left me feeling pleasantly confused, Acceptance left me feeling mostly just confused. Perhaps it's just natural to feel a bit unsatisfied at the end of a trilogy; I did enjoy reading the book while I was reading it, and I'm glad I read all of the books. I'll be buying them as gifts for friends who love scary stories.
