With a fatal bullet in her gut, Celina Leviet has only seconds to make a fateful decision. Join her murdered husband in death, or make a deal with a demon.

She doesn’t know how or why Mekaisto found her, but she doesn’t hesitate. In exchange for her soul, he’ll let her live long enough to wreak revenge. The catch? She must kill the murderers with her own hands.

The contract sealed, her skin carrying Mekaisto’s brand, Celina digs into her husband’s past. But every new revelation unravels everything about the man she loved. His company never existed. His family history was a lie. And he belonged to a shadowy religious order whose members know too much about demons.

Her emotions in shreds, she finds Mekaisto’s seductive charms harder to resist. But her dead husband’s secrets aren’t the only betrayal. As the final, shocking truth comes to light, she struggles with the darkest of choices—break her vow and surrender to the unknown, or succumb to the devil she knows.
