This is a weak 2.5 stars, and I'm a little mixed about it getting that much to be honest. I thought it was excellent. Right up until the end when it all went completely to shit. If it weren't for the truly awful ending -and even worse epilogue- that absolutely ruined the whole thing for me this could have been a 5 star read.
The story set up all these really interesting ramifications for the piper technology and the League that ran everything and the secrets that were being kept from the pipers themselves as well as the public and all the way through the book those were built up and built up and then apparently Carver decided "fuck it" because the end didn't bother to address any of it.
NOTHING to do with pipers or the League (or what they are actually doing or how aware they are of what pipers can or or ANYTHING about any of it) is addressed or resolved or even acknowledged again after a couple hundred pages of build up. So fuck that.
