In the dark world of the Moon Chasers, love and evil are separated by only a heartbeat as an undying lycan searches for the demon witch who cursed him.

For generations, the immortal Darius, doomed to roam the Earth as a lycan, has hunted the one responsible for his terrible fate. He is determined to exact revenge for the untold suffering Tresa has unleashed upon the world, but when the two finally come face-to-face, Darius discovers that she is not the purely evil creature he expected, but rather a tantalizing woman.

Determined to avoid causing further harm, Tresa has spent numberless centuries fleeing the demon who enslaved her. Tormented by the devastating mistakes of her past, she feels she has condemned herself to suffering. Certainly she does not deserve to find passion. . . . Yet it may be that only by becoming lovers will Darius and Tresa find a power that burns brighter than the dark forces arrayed against them, a love pure enough to at last bring them both the redemption that they crave.
