A human servant, Mara Vale, scrubs blood from the marble floors of Blackthorn Academy, a kingdom ruled by powerful, cruel vampires. She has learned to be invisible, to keep her head down, and never to let a vampire see her cry. But when the heir to the vampire throne, Prince Kael Veyr, catches her eye, her carefully constructed world shatters. He sees something in her blood, something that frightens even him, and suddenly, the girl who was once invisible is dragged into the heart of the royal court. What ancient power stirs within Mara's veins, and what dark destiny awaits her in a world where humans are merely prey?
