Violetta Valemont stepped into the elevator with a birthday cake in her hands, a bright smile dancing across her lips. Tonight was supposed to be perfect. Until the elevator doors opened on the thirteenth floor. She stepped out—and froze.

His eyes widened when he saw her. “Violetta... what are you doing here?” But before she could answer, a woman's voice came from behind her. “Because I called her.” Violetta slowly turned. The woman standing behind her smiled. Who is the woman? Why did she call Violetta? And what is Violetta's real identity?
