For all of Kat’s life, it’s been her and her mother, Jamie - except for 12 years ago, when Jamie was married for two days and Kat had a stepbrother, Liam. But all that ended in a swift divorce.

Now Jamie is a jewel thief trying to go straight, but she has one last job, at a billionaire's 80th birthday party. Neither Kat nor her mother know about two surprise guests: Liam and his father, a serial scammer with his own sights set on Ross Sutherland’s family.

Kat and Liam are on a collision course to disaster, and when someone dies, the two teens realize they might be in the killer’s crosshairs. They can’t trust anyone except each other.
