Four women-friends, family, rivals-turn to online dating for companionship, only to find themselves in the crosshairs of a tech-savvy killer using an app to target his victims in this harrowing thriller from the New York Times bestselling author of See Jane Run and The Bad Daughter.

Online dating is risky-will that message be a sweet greeting or an unsolicited lewd photo? Will he be as handsome in real life as he is in his photos, or were they taken ten years and twenty pounds ago? And when he asks you to go home with him, how do you know it's safe? The man calling himself "Mr. Right Now" in his profile knows that his perfect hair, winning smile, and charming banter put women at ease, silencing any doubts they might have about going back to his apartment. There, he has a special evening all planned out: steaks, wine, candlelight . . . and, by the end of the night, pain and a slow, agonizing death.

Driven to desperation-by divorce, boredom, infidelity, a beloved husband's death-a young woman named Paige, her cousin and rival Heather, her best friend, Chloe, and her mother, Joan, all decide to try their hand at online dating. They each download an app, hoping to right-swipe their way to love and happiness.

But one of them unwittingly makes a date with the killer, starting the clock on a race to save her life.

New York Times bestselling author Joy Fielding has written a complex, electrifying thriller about friendship, jealousy, and passion-a deadly combination.
