For Cassidy "Cas" Dubois, being forgotten is not just an unfortunate occurrence, it is her profession. Her born talent makes her a valuable asset to the supernatural community that would rather not have mortals remembering the strange occurrences that go on in Knoxville, Tennessee - the place she has lived for as long as she can recall. The unfortunate side effect of her ability is that very few people remember her - not even when she wants them to. That is until a new player arrives in town and takes a keen interest in her. Unfamiliar with such attention, Cas must reconcile her desire to get out of the life with the possibility of making a genuine connection with the first person to not forget her the moment they part. Her dilemma is forgotten when a job goes sideways and Cas finds herself in the role of investigator instead of just the cleanup crew. People with abilities - people like her - are going missing. Worse, whispers of war complicate matters. Something bad is brewing in the supernatural realm... Can Cas and the others figure it out before it's too late?
