Such Charming Liars by Karen M. McManus

When mother-daughter grifters set out on their final job, the heist gets dangerously personal ... and deadly.

For all of Kat’s life, it’s just been her and her mother, Jamie—except for the forty-eight hours twelve years ago when Jamie was married and Kat had a stepbrother, Liam. That all ended in an epic divorce, and Kat and Liam haven’t spoken since.

Now Jamie is a jewel thief trying to go straight, but she has one last job - at billionaire Ross Sutherland’s 80th birthday party - and Kat has figured out a way to tag along with her mother. What Kat doesn’t know, though, is that there are two more surprise guests at the dazzling Sutherland compound that weekend: Liam and his father, a serial scammer who has his sights set on Ross Sutherland’s daughter.

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

Or can they? Because if there’s one thing both Kat and Liam know, it’s how to lie. They learned from the best.
