“Remember the darkness. Only the darkness will save you.” As part of a deal with the god of night, Ursula is sent to the Shadow Realm. There, she must live in the forbidding palace of an ancient night demon. Granted--he seems to hate her. But he's easy on the eyes, powerful as hell, and he's supposed to keep her safe.

Worse--she may have to battle her own guardian, who has centuries of slaughter on his side. And only one can survive. In order to live, Ursula must learn to fight like a brutal shadow demon, and resist the dark temptations of the realm. If she fails, the god of night will drag her down into hell with him. less

Ursula hadn’t expected to return to the Shadow Realm a prisoner, but at least the dungeon reunites her with her old mentor, Kester. That’s only a small consolation when she learns the horrific plans of a shadowy demigod. Plans that involve her. In order to fight back, she must find her fiancé, Bael. Together, they've got to steal Excalibur from the world's most powerful dragon-shifter. On her journey, her shocking past is revealed, and Ursula finally learns the truth about herself... moreUrsula hadn’t expected to return to the Shadow Realm a prisoner, but at least the dungeon reunites her with her old mentor, Kester.
