Amelie Pearce, born into one of the prominent crime families in Chicago, is a princess of the mafia renowned for her physical attractiveness. However, what many perceive as a blessing becomes her downfall when she is compelled to marry Gio Locatelli, in order to establish peace between two mafia dynasties. Gio is the prospective head of the Locatelli Cartel within the New York Famiglia, a man infamous for his brutal nature and for strangling his cousin with his bare hands. Millie is filled with terror at the prospect of marrying such a monster. Despite being one of the most desirable bachelors in New York due to his good looks, wealth, and charismatic but predatory demeanor, Millie understands that Gio's bad boy persona is more than just an act. Behind Gio's captivating gray eyes and arrogant smile lie bloodshed and death. In her world, an attractive exterior often conceals a hidden monster—one capable of both killing and kissing with equal ease. However, escaping from the arranged union, let alone a man like Gio, is impossible. He would pursue her to the ends of the earth. Millie's only hope of survival in a marriage with Gio is to win his affection and gradually find her way into his heart—despite rumors that suggest Gio possesses no heart at all. A beautiful mafia princess given to a monstrous man. Even monsters harbor a heart. She fully intends to find her place within it.
