Looking for JJ — Anne Cassidy

Three children walked away from the cottages on the edge of town toward 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. 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. But Alice's past is dangerous, and violent, and sad . . . and it's about to rip her new life apart.
A gripping and emotionally searing novel by accomplished British author Anne Cassidy, Looking for JJ infuses a terrifying subject with humanity and hope.
