Calla Tor is a guardian, an Alpha female , for the Keepers. Ren, an Alpha male , has been matched with Calla since they were little to become "mates" and be the Alpha leaders of a wolf pack. When Calla breaks all the Keepers rules, usually punished by death, by saving a young boys life, she begins to question all that she has known. She continues to risk her life in search of answers and for love. I thought this book was interesting. I enjoyed the characters, but to me, it seemed Calla jumped in too quickly to do things she knew she would be killed for. As for Ren and the boy, I was torn between who she should chose. There was a lot of fighting and action. It was pretty clean, but had some kissing and a little touching.
