This was a great book for a lazy summer day. I finished it in one day. I liked the characters. Familiar feel to Hunger Games, which is something I like, but it wasn't too much like it. Story line keeps you reading and interested and wanting to find out what happens. I was very surprised to see the book change pace at Part Two and go from the enclave to topside. It felt very abrupt. For all the criticism of its plot lines, it was still enjoyable to read.
