The Familiar — Jill Nojack

Sometimes a cat has to man up. Tom has been mostly cat for a long time, but when the witch who enslaved him dies, he has one last chance to become a man again and maybe to find love, too. He just needs to tell Cassie, a sensible girl who knows nothing about the witchy business all around her, that he's trapped in the body of the kitten she cuddles at night. But cats aren't known for their conversational skills, and a powerful warlock is determined to take Cassie for himself. To make things worse, Tom is rapidly running out of lives. Note: The Bad Tom Series is rated PG-16 for non-graphic but "mature" themes.
