More than anything, Benjamin Ravenspell wants a pet. But when he buys a mouse named Amber, he gets more than he bargained for. No sooner does Ben take her home, than Amber turns him into a mouse too. You see, Amber has magical abilities, and it so happens that Ben is a familiar—a creature that stores magical energy. Together they each form half of a powerful wizard. Alone, they're just vermin.

Soon Ben and Amber will find themselves pitted in an epic battle against a magical enemy who is as crazed as he is evil, and the fate of the world will depend on them learning to work together.

David Farland has long been one of the writers of fantasy in the world. Now he gives us a marvelous book for young readers, one that is rooted in the deepest kind of moral vision.
