Darkest Pleasure 

Bound by the spirit of pain, he is forbidden to know pleasure… Reyes is at the mercy of a demon who demands suffering – a creature who once forced him to lay waste to the world. He has learned to satisfy it with his own pain, and now any joy in life has become impossible. His curse is even more intolerable when mortal woman Danika Ford enters his life.Danika is on the run. For months she’s eluded the Lords of the Underworld, the warriors who won’t rest until she and her family have been destroyed. Her dreams may be haunted by Reyes, but her only choice is to kill him before he kills her.
