From the much-praised author Fiona McPhillips (“Excruciating suspense” — Stephen King; “Shocking” —NYTBR), a novel of murder and betrayal, pulse-pounding music, and all the lives we leave behind

Annie Fagan, one of Ireland's first female electronic DJs and producers, spent her early twenties hosting and playing illegal raves across Ireland. Part of a legendary free party crew, she was surrounded by loud music, beautiful people, and the alluring chaos of the dance floor. But after one of their huge parties in the woods, Annie's friend Seán disappeared without a trace, and Annie gave up that part of herself for good.

Years later, when Seán's body is discovered in the Dublin mountains and new information about his disappearance comes to light, Annie reunites with her old group of friends—led by Fran Baker, the man she once believed she was destined to end up with—and feels inexplicably drawn back into the scene. Annie—and the police—starts to realize that, far from a tragic accident or random misadventure, Seán's death must have been caused by someone who was at their party. Someone who had a motive.

One of her friends.

As Annie investigates, her new and old worlds clash, another old friend is silenced, and she realizes that some people may not want the mystery of Seán's death to be solved. In fact, they might do anything to stop her from discovering what happened that night, when the party truly ended.
