In public, the werewolf prince is my bodyguard. But in private, I'm his slave.

Calys Adelardi has made two promises for the good of her pack. One is to marry Pasquale, a boring but well-respected panther prince. Second is to follow everything her bodyguard says in the bedroom. The werewolf prince may be a notorious playboy, but he's also the fiercest fighter she knows. In truth, her bodyguard would have also made great husband material - if only he didn't hate her so much.
Alejandro Moretti is determined not to fall in love with Calys, the princess also known as the "human monster". But then a serious threat to her life emerges, and Alejandro realizes he has to make a decision once and for all: give in to his feelings…or turn his back on Calys to protect his heart.
