In 2009, Edie had New York's social world in her thrall. Mercurial and beguiling, she was the shining star of a group of recent graduates living in a Brooklyn loft and treating New York like their playground. When Edie's body was found near a suicide note at the end of a long, drunken night, no one could believe it. Grief, shock, and resentment scattered the group and brought the era to an abrupt end. A decade later, Lindsay has come a long way from the drug-addled world of Calhoun Lofts. She has devoted best friends, a cozy apartment, and a thriving career as a magazine's head fact-checker. But when a chance reunion leads Lindsay to discover an unsettling video from that hazy night, she starts to wonder if Edie was actually murdered--and, worse, if she herself was involved. As she rifles through those months in 2009--combing through case files, old technology, and her fractured memories--Lindsay is forced to confront the demons of her own violent history to bring the truth to light.
