Dani O’Malley walks the shadowy streets of Dublin, scars etched deep into her flesh and soul. Transformed into a ruthless killer at the tender age of nine by the sadistic Rowena, she has become both the city's guardian angel and its most feared hunter.

By day, she rescues the lost and protects the innocent. By night, she stalks the darkness, dispensing swift justice against encroaching evil. But a new terror rises from the depths—the aftermath of the Faerie Queen's powerful Song of Making has awakened horrifying forces bent on enslaving humanity and unleashing hell on earth.

Armed with the legendary Sword of Light and joined by the immortal Ryodan, Dani must confront her haunted past to wield the power necessary to save mankind. But the cost may be more than she can bear. As deadly enemies close in, demanding an unspeakable price, will Dani sacrifice everything to prevent the dawn of eternal darkness?
