I really enjoyed this book. The only reason I didn't give it five is because I have some issues with certain scenes. It took me a couple tries to get into this book but once I did I found myself enjoying it and finished it quickly.
The school is for shifters, not callers, so Caleb is a little on the outside. The teacher, Morfael, is also a caller and teaches the shifters the everything the shifters need to know. Dez is an outsider at first and Caleb is unwelcome. The prejudice between the callers and the other shifters is extremely obvious. It's sad really.
There is something special about Dez and even at the end of the book we don't really know what's going on with her or what she truly is. But because she was never raised around other shifters, she does not have the prejudice that they all have. She is able to bring everyone together and become friends. This is something that never happens.
What I didn't like was some of the writing and reactions. Dez finds out about this other world and she's not as freaked out as I think she should be. If I had changed into a tiger and then kidnapped and shoved into a cage, I think I'd be freaking out more than she actually was. Sometimes the writing seemed rushed. Despite these issues I really enjoyed this book.
I would recommend it to anyone who enjoys shapeshifter books and want a different take on a fantasy world. The topic of shapeshifters has been used many times and I like that this book used it and changed it into something completely different than anything I was expecting.
