Angel

As if being the only human with wings wasn't enough, Angel learns that she can shapeshift into a cheetah. Terrified by her transformation, Angel's mother abandons her on the side of the road. Hungry and alone, Angel befriends a boy named Justin. They discover that Angel can change into almost any animal she can think of. Before long, a stranger approaches them. She claims to know why Angel was created: to kill the devil. There is no way two kids could be capable of such a thing. . . right?
