Katherine Luna lives in Sleepy Hollow. And she is upset with her life. She is being forced to go to a different high school than all her friends, the creepy cat lady who lives in her neighborhood is getting stranger each day and she has just been humiliated at a senior party on Halloween in the worst way possible for a teenage girl. As her body suddenly begins to change in the most unexpected way, forcing all the boys to fawn over her, she is confronted with the realization that she can communicate with cats, and that a mysterious man is now following her. All starts to make sense when she learns that she has become a Felinian and that she has been quickly gifted with the fabled nine lives of a cat, tied somehow with ancient Egyptian lore, and empowered with the ability to control the passions and minds of men. As Katherine fights her lustful, Felinian nature, attempting to stop herself from stalking the boys of her school, the man stalking her begins to reveal his purpose. With the help of her neighborhood friend, Hector, a boy who seems more connected to this haunted world than he lets on, Katherine tries to manage her new life and struggles to strike a balance between monster and girl, all the while hoping and wondering, will she ever be a regular girl again?
