Thrust into the ancient world of vampires, Lilith realizes that the nighttime immortals have been keeping dangerous secrets.

Lives are broken or made on that one, mystical substance—something Adrienne Valois knows all too well. Revered in Oylen’s black market as “the jewel of the Souzterain” Adrienne is all too aware the second most important thing in this world is beauty. And hers is a siren call to powerful blood drinkers. Adrienne finds herself trapped between two immortals who vie for her attention—one a patron of the blood den she works and the other the oldest vampire in the world, Lord Eamon Azad. Though she believes Eamon merely wants what runs in her veins, nothing could be further from the truth. But after years witnessing the darker side to Oylen’s vampire elite, trusting the promises of a mysterious ancient immortal feels as dangerous as placing her palm over a flame. Either way, she would be burned. less
