Lost Girls is a portrait of unsolved murders in an idyllic part of America, of the underside of the Internet, and of the secrets we keep without admitting to ourselves that we keep them. Long considered "one of the best true-crime books of all time" (Time), this edition includes a new epilogue that speaks to developments in the case, including the shocking fate of Mari Gilbert, Shannan's mother, for whom this case became the crusade of a lifetime.
