The Locked Ward is the latest twisty thriller from #1 New York Times bestselling author of Gone Tonight and House of Glass, Sarah Pekkanen.

Was it bitter, all-consuming jealousy? Pathological sibling rivalry? Pure insanity? Whatever the cause - and everyone has a theory- it was the Crime of the Decade when glamorous Georgia Cartwright, who was adopted as a newborn, killed the younger, biological daughter of her wealthy, Southern family.

Georgia is locked in a psychiatric institution where the most violent offenders are held while she awaits trial. The only words she whispers when her estranged twin sister Amanda visits are, "You've got to get me out of here. I didn't do it." Amanda doesn't trust Georgia, but she can't abandon her in a place so eerie and menacing it seems to exist in another dimension.

Is Georgia the victim of a powerful family so depraved that murder is the least of their crimes? Or is Amanda being led down a path of madness and into the web of a master manipulator?
