Well, at least that series is over with.
The first two books in the Forest of Hands and Teeth series were interesting and fun. This book just felt tired. Tired and bored, like the author didn't even care all that much and just wrote it out of obligation. The "love triangle" really wasn't (which, honestly, is good), the angst was weak, the bad guys were all pretty boring and one dimensional, and even the good guys bored me.
For the ending of a trilogy it was rather unsatisfying. It could almost be a standalone novel (if there weren't some minor back story from the first two), and it didn't answer any questions or give any benefits to those who made it through the whole series. Meh.
