The angel and demon may war within him, but it's her that will be his sweet ruin. Declan Cain isn't who-or what-he pretends to be. Son of the demon king and the last living Nephilim, he struggles to find a balance between his warring natures. His internal fight only intensifies the night he walks into a diner and sees her. The incubus wants to seduce her and devour her lust, and the angel is determined to protect her from her greatest threat-him. Alexandria Sade has left behind her sheltered life and is eager to experience everything she's missed out on. She never imagined that her newfound freedom would place her in the path of a handsome stranger who's willing to help her explore her darkest desires. Nor does Lexie realize that she's now the willing prey for an incubus. Little do Declan and Lexie know that their intense connection plays right into the hands of the demon king. Lexie will become his bargaining chip to persuade his son to steal the thing that will give him the power to rip apart the veils between the human, demon, and angel realms. With nothing stopping King Rimmon, he will destroy the world as they know it, leaving Declan to choose between saving all humanity or watching it burn for the woman he loves.
