"Faruq Zaidi, a young journalist reeling from the recent death of his father, a devout Muslim, takes the opportunity to embed in a cult called The Nameless. Based in the California redwoods and shepherded by an enigmatic Vietnam War-veteran named Odo, The Nameless adhere to the 18 Utterances, including teachings such as "There is no god but the nameless," "All suffering is distortion," and "See only beauty." Faruq, skeptical but committed to unraveling the mystery of The Nameless, extends his stay over months, as he gets deeper into the cult's inner workings, compassionate teachings, and closer to Odo. Faruq himself begins to unravel, forced to come-to-terms with the memories he has been running from while trying to resist Odo's spell. Told in three seamlessly interwoven threads between Faruq's present-day investigation, Odo's time before the formation of the movement as a Black infantryman during the Vietnam War, alongside three other Black soldiers, and a documentary script that recounts The Nameless' clash with a Texan fundamentalist church, O sinners! examines both longing and belonging. Ultimately the novel asks: What is it that we seek from cults and, inevitably, from each other?"--
