Ancient Secrets, Dark Passions...

As one of the Grigori, a noble vampire dynasty shrouded in mystery, Ariane has spent her life hidden away in the desert. Like all of her kind, she is a watcher, fated to observe, forbidden to act. Yet when her best friend, Sammael, vanishes, she defies all rules and flees her safe haven to bring him home.

A shape-shifting assassin for the House of Shadows, Damien Tremaine is hired to locate Sammael. His hunt for the wayward Grigori leads him to Ariane, the rogue vamp who stands between him and his bounty. Damien never lets emotion interfere with his work, but a single touch from the sexy, beguiling vampire shatters his self-control. Drawn together by their common goal, what begins as an alliance of necessity soon becomes one of desire. But when the secret at the dark heart of the Grigori comes to light, Damien and Ariane must make a choice that could bind them eternally...or tear them—and everything they care about—apart.
