"Frankie Elkin, who readers first met in Before She Disappeared, learns of a young man who has gone missing in a national forest. Law enforcement has abandoned the search, but a crew of people led by the young man's father are still looking. Sensing a father's desperation, Frankie agrees to help--but soon sees that a missing person isn't all that's wrong here. And when more people start to vanish, Frankie realizes she's up against something very dark--and she's running out of time. Timothy O'Day knew the woods, yet went missing without a trace on the first night of a bachelor party camping trip in the wilderness of Wyoming. Frankie Elkin doesn't know the woods, but she knows how to find people. Despite the rescue team's reluctance, she joins them. But it soon becomes clear that there's something dangerous at work in the woods... or someone who is willing to do anything to stop them from going any farther." -- adapted from cover.
