This book was a fast and engaging read, and I can't wait to read the rest of them.

Phoebe not being human is really interesting twist. I'm not sure how I feel about the only hinting about her being different from the other kids being a disability, but I do like that she was never excluded from anything by her friends. I'm curious how the next book will resolve the sabotage plot lines. There are only two more books in this series, and I'm not sure that they can fit everything that I want from the rest of this series within them, but I'm looking forward to figuring that out.

This book uniquely and very interestingly frames the end of the world as you know it as something that is very much not the worst case scenario.
