I didn't expect much from this book - I picked it up when I really needed something to read. I have tried to read some of P.C. Cast's goddesses series and hated them (her prose just didn't work for me). But this book is different: I haven't finished the last 100 pages yet (I've had an essay to do today!) and I have already ordered the next book Betrayed.
The book starts out very 'Meg Cabot': "Just when I thought my day couldn't get any worse I saw the dead guy standing next to my locker." But it quickly develops a style of its own. Zoey's world really starts to develop once she gets to the academy. N.B. Do not buy this book for you 13 year old cousin - there is some adult content (and I'm not talking about blood sucking). There's romance, mystery, action and theory.
I have enjoyed this book alot - I think P.C. Cast and her daughter make a brilliant team and I would buy any future book they write together! The storyline is interesting and new. My taste runs: Meg Cabot, Elizabeth Chandler, L J Smith, R J Ward, Sherrilyn Kenyon, Laurell K Hamilton etc. So if you've read any of these authors - they are my judging standard! This is meant to be a book for adult teenagers, Zoey is only 16 in the book, but I'm 19 and really enjoyed it. There were Harry Potter undertones, but only in the classroom settings - the context the Casts place the characters in is completely different - which would be hard to avoid. This book is fresh and new, and the prose invite you to empathize with Zoey. I loved this book, if I hadn't this review would be alot shorter.
Anyway - this is my recommendation: buy this book and read at least the first 100 pages before you judge it (as it is slow to develop into its true shinning potential!). The only reason that this book hasn't received more than 4 stars was it's slow beginning: I predict that all further books in the series will be 5 stars! Hope this review was helpful!
