I mostly enjoyed this. I know that, as a YA/middle grade level book, it's supposed to be short, and that's fine, but it could have used a little bit more length, I think. And while I didn't dislike the ending, it was so damn abrupt. I borrowed the ebook from my library, so I didn't realize I had come to the end until I couldn't turn the page anymore. I think there could have been just a little more after. I didn't dislike Matty, but I didn't like him as much as Kira and Jonas in the previous books (or even as much as his younger, more mischievous self).
