"A thrilling survival story about two teens just trying to make it to daybreak with their friendship--and their lives, too, as a horror beyond their wildest dreams lurks in the forest." --Booklist Bears aren't the only predators in these woods. Best friends Neena and Josie spent high school as outsiders, but at least they had each other. Now, with college and a two-thousand-mile separation looming on the horizon, they have one last chance to be together--a three-day hike deep into the woods of the Pisgah National Forest. Simmering tensions lead to a detour off the trail and straight into a waking nightmare ... and then into something far worse. Something that will test them in horrifying ways. Stephanie Perkins, the bestselling author of There's Someone Inside Your House, returns with a heart-stopping, gut-wrenching novel about friendship, survival, and navigating unmarked paths even as evil watches from the shadows.
