I liked the book. The counting bit of Ten's was a bit annoying but I dealt with it. I liked the story and the overall idea of the book. I am sadden that it'll be a long time before the next one. One of the downsides was that my eyes sorta glazed over for part of it, like I read the part but I didn't really read it. 
 I will end up rereading this one day and of course I'll be waiting for the next book to come out. 
 Good job Gena Showalter for keeping me engaged and not making it too predictable.
