I enjoyed this book, it was a bit hard to read in the beginning because the characters are literally being tortured, but I thought it was a pretty interesting world building book, it expanded on the first one a lot to make the whole "superpowers" thing be more filled out and the central romance was something I really believed. Though there is something a bit lacking that (having read the third one too) I keep missing in these books. I enjoy them but can't put my finger on why I'm not raving about them. Well, I'll keep reading and try to figure it out :)
