Shadow's Mercy

Aria Castellano was bred to be the perfect weapon, a shadow-walker trained from childhood to kill for her mafia family using both blade and dark magic. But when she hesitates to execute Dante Moretti, the psychic heir of their rival family, that moment of mercy destroys everything. Five years later, striped off her memories and powers, leaving her vulnerable and human. Dante, who has spent years building his own supernatural empire while plotting revenge, finally has her in his grasp. But the broken, gentle woman he captures bears no resemblance to the deadly assassin who spared his life.
