The acclaimed author of the “tour de force” (The New York Times Book Review) Before You Knew My Name returns with a fresh suspense novel about a woman haunted by a serial killer and the ghosts he left behind. Ruth-Ann Baker is a college dropout, a bartender—and an amateur detective who just can’t stay away from true crime. Nineteen years ago, her childhood friend was murdered by suspected serial killer Ethan Oswald. Still tormented by the case, Ruth can’t help but think of the long-dead Oswald when another young girl goes missing from the same town. And when she uncovers startling new evidence that suggests Oswald did not act alone, she is determined to find his deadly partner in crime. Embarking on a global investigation, Ruth becomes close to three very different women—one of whom might just hold the key to what happened to the missing girl. And her childhood friend, all those years ago. From an author who “pushes the boundaries of crime fiction in all the right ways” (Alex Finlay, author of The Night Shift), Leave the Girls Behind is another spine-chilling thriller that will linger long after you finish the last page.
