I consider it a bridge between a really good book and another really good book. The bridge has to be strong, but it also needs to lead from the first one to the second one--so some things make absolutely no sense, and tons of new characters have to be introduced. Overall I give it a 4 out of 5: EXCELLENT PLOT OMG. I love how it's split narration between almost all of the characters in the whole story, which you don't find a lot of in these kinds of books. The author is Marissa Meyer and she's amazing. I recommend :)
