From the bestselling author of I Am Still Alive comes a new nail-biter that's part survival story, part murder mystery, and all thriller—perfect for fans of Karen McManus and Holly Jackson!

Two years ago, Mercy Gray was hailed as a hero for saving lives during a mall shooting. She still carries souvenirs from that incident: the fragment of a bullet lodged in her back, a mountain of medical debt, and guilt for ignoring her sister’s warnings that the sweet boy next door was anything but.

When billionaire-turned-TV-host Damien Dare recruits Mercy to compete on his new survivalist reality show, she can’t turn down a chance at the whopping cash prize that could send her sister to college. But when she and the other contestants arrive at the off-grid location, something isn’t right. The set is empty. The gates close without warning, trapping them inside. Then one of them turns up dead. What appeared at first to be a tragic accident quickly transforms as more contestants start dying. With time and resources running low, surviving this show takes on a new meaning.
