It's been seven years since Else visited her tiny hometown on an isolated island off the coast of Scotland. After years of suffering bullying at the hands of the few other residents, she left to make a new life. But now that her mother has passed, Else has returned. And when her old tormentor Karen Little hands her the very book that sent her running all those years ago, the cruelties of her past have Else seeing red.
