When Lance Treadwell volunteers for a fire-watch post deep in the Appalachian backcountry, he expects solitude and quiet—just a week alone in an aging tower keeping an eye out for smoke. But after a routine check on a dead radio repeater, he realizes something else is in those woods. Something that doesn’t want him there. As the isolation tightens and night falls, Lance learns that some places are watched for reasons no map will ever show… and not every lookout is meant to return.
