There was some things like I disliked, like the fact that Sarah turned John in. I felt that was OOC for her. Especially of everything that went down in the first book. That never made any sense to me, unless there is more to that story than that. Like she was forced to, by maybe the police or something.
But other than that, I thought the book was great. Loved seeing the others. Like Number 7, 10 and 9 (Toward the end).
