Three children walked away from the cottages on the edge of the town towards Berwick Waters. Later that day only two of them came back. Alice Tully knows exactly what happened that spring day six years ago - though it's still hard for her to believe it's real. She'll never be able to forget, even though she's trying to lead a normal life - she has a job, friends and a boyfriend whom she adores. She's making a go of things, putting her past behind her at last. But Alice's past is dangerous, and violent, and sad - and it's about to rip her new life apart.
