As a goblin prince living in the human court of Morvane, Luc is unerringly loyal to his best friend, Prince Ramon. While his feelings seem genuine, his loyalty is forced, magically-controlled by the false heart beating in his chest. The royal wizards have hidden his true heart out of reach, keeping Luc as a well-mannered captive in the Morvanish palace.

Will Fletcher is an irritable apprentice smith, more comfortable sneaking off to the goblin kingdom of the Brightwood than staying in his family home. When Luc stumbles into his life, Will learns that he and the goblin prince have more in common than he expects. In order to steal back Luc's heart and free him from magical bondage, Will must confront the shadows hiding in his past and forge a new life.
