Lucinda, Darkly: The Demon Princess Chronicles

For centuries, Lucinda has dwelt in eternal darkness. As a demon princess, daughter of the High Lord of Hell, she exists in an endless, joyless realm - ruling over nothing, retrieving the occasional wayward demon and feeding off the savage Monere of whom she was a member before she died. Then she meets a Monere warrior, Stefan, who offers himself to her. She is moved beyond measure by her desire for him - and soon finds herself drawn back into the heady eroticism of the Monere.
