Rhys spent centuries alone, fighting the darkness he carries within. Forced to be a servant of Death, he is a dullahan—one of the creatures that originated the Headless Horseman myth. The only thing he wants—and can’t have—is to die. Until a strange woman with no memories comes to his life, bringing back the painful past he buried long ago.

Tamerah doesn’t know who she is and doesn’t remember anything, except for this: she is Rhys’s last hope. If he doesn’t accept her help, the darkness will be unleashed upon the world and humankind will be destroyed.
