It is in the course of her duties as a doctor's assistant that Genevieve first encounters the Guild, a militant organization of formidable men. Her encounter is in the form of an enigmatic man named Roan Phillips. If Roan were typical of the Guild, the only thing Genevieve would have to worry about is losing her heart. But unfortunately, it turns out another man, the sadistic Gregory, is far more typical of the Guild. And because of him, Genevieve is at high risk of losing her life.
