For years, rumors of the “hairy beast” have haunted the woods of Missouri, a Midwestern state filled with river bluffs and caves. So in late 2014, when housewife and mother Emily is discovered missing, the locals immediately suspect Dave, her ex-husband. But Emily is not where they believe. Sensitive and humorous, she has survived for weeks alone in the new underground area that she calls home, finding new friendships in the dirt-filled paths and caves. Then the time comes to become Stem’s mate. He becomes intrigued by her wild beauty and Emily opens herself to a new life – until the unthinkable happens.
