In the summer of 1977, best friends Heather and Brenda witness something in the dark tunnels beneath their small Minnesota town. They’ve sworn never to speak of it again. But when their friend disappears—the second girl in a week—Heather fears their secret holds the key.
As local authorities remain indifferent, Heather takes matters into her own hands, uncovering chilling truths about her community. No one is who they seem—not the police, not the boys at the quarry, not even her parents.
Now, Heather must uncover the truth before it’s too late. Because the deeper she digs, the clearer it becomes: she’s the next to disappear.
Can Heather save herself before the secrets consume her?
