To save her sister from Marco De Luca, Elena signs a 90-night deal with Damian Voss: the city’s devil in a black suit. Rule 1: No love. Rule 2: No questions. Rule 3: Be home by 3am. The job is simple. Live in his penthouse. Work for him. Stay alive. In return, he destroys Marco and gives her sister freedom. But the red light changes everything. The late-night drives. The way he stands between her and danger. The red silk scarf left on her chair like a warning and a promise. By Night 47, Elena sees the man under the monster. By Night 68, Marco finds them. By Night 89, the contract ends. Walking away means safety. Staying means Damian. And devils don’t let go easy.
