Ten years ago, Orien, crown prince of the Seleighe, was captured by his mortal enemies, locked in a dungeon, and turned into a vampire. Four years ago, Cullen, a Healer's brother, disobeyed his Mistress' orders, thus sealing his fate for all eternity. Now, they both are free. But a secret only Cullen knows lies locked inside his mind, and it might drive him mad before he can uncover the identity of a traitor--the elf who betrayed Orien and left them both to die in darkness.
