Cassie is a 17 she is half angel and on top of that she has magical powers. Her little 5 year old sister is also half angel & has magical powers. What happens when these 2 end up on their own because of home situations. Aiden Calway is what happens. He is a Werewolf who doesn't know that Cassie is his mate. It's ironic how she knows and he doesn't. I mean he's the wolf he should know and she shouldn't know but I guess Aiden will just have to wait to find out where her secret lies.
