Unseen (The Heights, Vol. 1)

Job security isn’t something Addison’s concerned with. Death, however? Yeah, death's a major concern. All she wants is for the half-dusted vampire she found to die. All Rhyse wants is to find out who tried to kill him. Neither of them wanted the danger their partnership brings. A vampire king and a woman who doesn't know she has the power to destroy the entire supernatural world--not a good match.
