When wolf-shifter Kelsey Yates discovers that fourteen-year-old shape-shifter Danny Harding is living with a human adoptive mother, she is sent on a secret mission to protect the pup and get him away from the human.

Successful CEO Rue Harding has no idea that the private teacher she hires for her deaf son isn't really there to teach him history and algebra-or that Danny and Kelsey are not what they seem to be.

But when Danny runs away from home and gets lost in New York City, Kelsey and Rue have to work together to find him before his first transformation sets in and reveals the shape-shifter's secret existence to the world.
