It was the Crime of the Decade. Pathological sibling rivalry. Bitter, all- consuming envy. Whatever the cause - and everyone has an opinion - it led Georgia Cartwright who was adopted as a newborn, to kill the younger, biological daughter of her wealthy, socially prominent family.

Georgia is being kept at an institution where the most violent offenders are held while she waits to see if she is ruled not guilty by reason of insanity. When her estranged twin sister, Amanda, visits her, Georgia's first words are, "You've got to get me out of here. I didn't do it." Her sister can’t walk away. There has always been a part of her that feels missing a strange hollowness that she has hidden from everyone.

Does it exist because of the absence of her twin sister? Can Amanda really trust Georgia? Or is she being led down a path of madness and into the web of a master manipulator. Nothing is as it seems in Sarah Pekkanen's new psychological thriller, The Locked Ward.
