Fortunately, Devota is reborn as an orphaned child named Diamond, and by sheer chance, she is taken in by a former ally, now a prominent duchess. The entire family treats her with love and affection, as if she was one of their own kin. It is possible, though, that she actually is a relative. However, with her killer still at large, and her quest for vengeance incomplete, can Diamond allow herself to love anyone again?
