"48 hours. That's all you get." Avery Monroe thought the past was buried. Until the bodies started appearing. In a locked facility no one can trace, eight people wake up in numbered rooms—each with a camera, a cot, and a clock counting down. Every one of them played a role in Lisa Marek's death. Every one of them thought no one would notice. Now they've got 48 hours to tell the truth… or die. As the hours vanish and secrets unravel, Avery must face not only what happened to Lisa—but what he did to survive it. Because someone out there is keeping score. And the truth isn't just dangerous. It's fatal. Perfect for fans of Saw , Before I Go to Sleep , and Behind Closed Doors , Hour 48 is a gripping psychological thriller about silence, guilt, and the price of looking away.
