A Bestselling Novelist’s book comes back to haunt her.

Kayleigh Carter is starting her life over above a coffee shop in Manhattan. She is also the author of the hit thriller My Legal Guardian, in which a “bad boy billionaire” plays Fifty Shades of Grey-style mind games on a female protagonist.

She discovers her apartment's previous tenant, a young college girl, went missing—the inspiration for her next thriller. However, someone doesn’t want her found, and she soon attracts a psychopath who is one step ahead of her, leaving messages signed XXX.

The deeper Kayleigh delves into the missing girl’s disappearance, the more factors point to her own book.

A pointedly thrilling sequence of psychological revelations and an ending you’ll never see coming.
