This is a tough one for me. I liked it but was a little frustrated by the final twenty pages or so. I'm pretty sure I have no idea what happened in the book, but I'm not too bothered by that fact, since our narrator clearly doesn't know either and I'm not sure she would tell us if she did. Having said that, Annihilation is genuinely unsettling, especially the first third, and it's pretty hard to creep me out. Well done throughout, don't get me wrong, I just wish I'd had a better sense of where I was headed...or being led to.
