A missing father. A lifetime of secrets. An ancient evil. Twenty-one-year-old Daniel Wester graduated from college two months ago. He has a bachelor's degree in history, a pile of student loan debt, and no job prospects in sight. When his dad mysteriously vanishes from inside their locked home, Daniel finds an old wooden box covered in strange symbols, a creepy collection of books about demonology, instructions to find an aunt he's never met, and driving directions that lead him halfway across the United States to a threatening iron security fence in the middle of nowhere. Daniel makes the journey there with his lifelong best friend, Lena, a recent nursing school graduate. On the other side of the fence, they discover a secret colony of demon hunters- a community his father abandoned decades ago, they tell him, though Dad never once mentioned this place to him. Daniel's reality is flipped upside down as he, Lena, and the members of this mysterious off-the-grid community team up to find his father- and battle the demon they believe took him.
