Echo Sullivan has all but given up on herself, and on men, until she meets her charming new neighbor, Flynn. An invitation to his Halloween Fantasy Ball sets her on a course of discovery, and sexual awakening with life-altering choices. Flynn's rakish good looks, sharp wit, and smooth Irish brogue appear to be just what the doctor ordered. He possesses an unsettling ability to recognize, and illuminate Echo's deepest desires; to stir them up and bring them bubbling to the surface. But Flynn harbors a strange and extraordinary secret. What would you say if someone offered you the world...but asked for your soul?
