One late spring evening in 2010, Shannan Gilbert, after running through the oceanfront community of Oak Beach screaming for her life, went missing. No one who had heard of her disappearance thought much about what had happened to the twenty-four-year-old: she was a Craigslist prostitute who had been fleeing a scene—of what, no one could be sure. The Suffolk County Police, too, seemed to have paid little attention—until seven months later, when an unexpected discovery in a bramble alongside a nearby highway turned up four bodies, all evenly spaced, all wrapped in burlap. But none of them Shannan's.
There was Maureen Brainard-Barnes, last seen at Penn Station in Manhattan three years earlier, and Melissa Barthelemy, last seen in the Bronx in 2009. There was Megan Waterman, last seen leaving a hotel in Hauppage, Long Island, just a month after Shannan's disappearance in 2010, and Amber Lynn Costello, last seen leaving a house in West Babylon a few months later that same year. Like Shannan, all four women were petite and in their twenties, they all came from out of town to work as escorts, and they all advertised on Craigslist and its competitor, Backpage.
 Lost Girls is a portrait not just of five women, but of unsolved murder 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. LOST GIRLS-AN UNSOLVED AMERICAN MYSTERY-Robert Kolker
