All she's ever wanted to do is forget where she came from. Too bad everyone else wants her to remember.

Twenty years ago, Isabelle DiSanto ceased to exist, and Sloane Matthews took her place. Since then, she's spent her life hoping the world would forget all about her former identity and leave her alone. She never wanted to be the heir to a serial killer dynasty, but someone else does, and they want to make Sloane pay for turning her back on the DiSanto name.

Special Agent James Cade knew keeping the Roman Numeral Killer a secret from Sloane would backfire on him and the FBI, but he couldn't do anything to stop it. Now that she knows the truth, she won't stop until they catch whoever is holding her past against her, and all Cade can do is hope she'll continue to work with him despite his lies.

Threatening her loved ones was his first mistake. Killing her neighbor would be his last. No matter how hard she's tried to stay hidden, Sloane's been thrust into a fight she never wanted to be in, but one she plans on winning at all costs.

Can Sloane keep it together long enough to catch the killer obsessed with her and the people she loves? Or will her new opponent prove to be too much to handle?
