Alison is as close to anonymous as she can get: with no ties, no home, a backroom job, hers is a life lived under the radar. She's a nobody; she has no-one and that's how she wants it. But once Alison was someone else: once she was Esme Grace, a teenager whose bedroom sat at the top of a remote and dilapidated house on the edge of a bleak estuary. A girl whose family, if not happy, exactly, was no unhappier than anyone else's—or so she thought. Then one night a terrible thing happened in the crooked house, a nightmare of violence out of which Alison emerged the only witness and sole survivor and from which she has been running ever since. Only when she meets academic Paul Bartlett does Alison realize that if she's to have any chance of happiness, she has to return to her old life and confront the darkness that worked its way inside her family and has pursued her ever since.
