Demon's Destiny is book one of the Dark City Guardians.
Garrett Duex Sabres is handsome, wealthy, brilliant and a demon with a split personality feeding on the living energy of humans. However, unlike others of his kind, Garrett chooses not to feed off pain and misery, he’s discovered a more palatable and just as potent source—sexual energy. Exploiting his charms, Garrett spends many evenings moving from one “dinner-date” to the next siphoning off small amounts from willing playmates. When Kay walks into Garrett’s life, his entire world is flipped around.
