Calys Adelardi, the princess also known as "the human monster", may only be alpha if she can find a strong, kind warrior to champion her cause. She’s determined to marry for the good of her pack, but meeting a playboy werewolf prince makes Calys think twice about her noble priorities. His name is Alejandro Moretti. He’s the strongest shifter she’s ever met, but he seems prouder of his skills in bed than in battle. When he tells her he’d be her Cavaliere, Calys is overjoyed…until she finds out his offer comes with a price. For every instance he does his duty, Alejandro expects Calys to pay it in his bed, whenever and wherever he wants.
