I think this book is fantastic. It grabs you from the beginning and carries you right through to the end with supernatural and crazy! This take on witches is one of the best I've read in a lot time. There is a lot going on in this book and it kept me turning the pages. The plot stalls a little bit in the middle in my opinion. In the beginning you get a lot of information and background then it slows a little bit before the climatic ending. It wasn't enough to make me put this book down though.
Ethan is one of my favorite male characters in a YA book in a long time. I haven't read many great dynamic male voices in a long time. Ethan is smart and he feels genuine which makes him easy to connect to. I think all of the characters in this book felt fleshed out and real. Even some of the supporting characters have clear motivations and backgrounds (like Link) that make their actions have meaning.
This book maybe all about Casters and magic, but it hits on some tough issues like desiring to fit in and bullying. I thought that Ethan and Lena tackle these issues in great ways and their relationship grows even stronger because of these struggles.
I can't wait to start the next book and see where these two go from here.
