Such Charming Liars by Karen M. McManus

From international bestselling author and the QUEEN OF TEEN CRIME Karen McManus comes a brand-new, explosive YA thriller.

The new mystery thriller from the author of One of Us Is Lying, Karen M. McManus! When mother-daughter grifters set out on their final heist, the job gets dangerously personal ... and deadly. 

For all of Kat's life, it's just been her and her mother, Jamie-except for forty-eight hours twelve years ago when Jamie was married and Kat had a stepbrother, Liam. That all ended in a swift 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. Kat has figured out a way to tag along to the dazzling Sutherland compound, but neither she nor her mother know about the other surprise guests that weekend- Liam and his father, a serial scammer who has his own sights set on Ross Sutherland's youngest 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.
