Dark Harbinger: Dirty Little Secrets

Twenty year old Quinn is an assassin who works for FACELESS, a group of mysterious individuals who pay handsomely for the deaths of their enemies.
Quinn isn't your typical assassin, she hides a deadly secret, a secret that FACELESS has weaponized. Quinn shares her soul with an evil entity, a succubus. It's her job to seduce the men FACELESS wants eliminated, allowing the curse of the succubus to devour the man's soul through intercourse.
Quinn's first assignment is Malachi Wilhelm, a charming and mysterious man who has an uncanny way with words. Can she fight off her feelings for her first target, or will she abandoned the FACELESS and become their next target!
