Lo Denham is used to being on her own. After her parents died, Lo's sister, Bea, joined The Unity Project, leaving Lo in the care of their great aunt. Thanks to its extensive charitable work, The Unity Project has won the hearts and minds of most in Upstate New York, but Lo knows there's more to the group than meets the eye. She's spent the last six years of her life trying - and failing - to prove it. When a man shows up at the magazine Lo works for claiming The Unity Project killed his son, Lo sees the perfect opportunity to expose the group and reunite with Bea. But as Lo delves deeper into The Project, it upends everything she thought she knew about her sister, herself, cults, and the world around her.
