The Grigori are a vampire dynasty shrouded in mystery. Ancient and stoic, they keep themselves separate from much of the world of night, instead watching silently as their brethren rise and fall. But with the disappearance of one of the dynasty's most important leaders, one determined Grigori will pair up with the unlikeliest of companions to save him. Ariane has spent her life sheltered, hidden away amid the desert sands with the rest of her kind, hungering for a life she has never known. When the man she considers one of her few true friends vanishes and her request to help in the search is denied, she takes matters into her own hands, determined to finally make a difference in a world she both fears and longs for. Damien Tremaine is a master thief and assassin, hired by the Grigori themselves, who will do anything for a price. As circumstances force Ariane and Damien ever closer together, what begins as an alliance of necessity quickly becomes one of need and finding what they seek may bind them eternally...or tear them, and everything they care about, apart.
