The Oracle's Daughter: A Woman's Escape From Her Mother's Cult
On a cool autumn night in 1999, twenty-six-year-old Sarah Green crept out of her house and ran for her life. She was escaping not just the Aggressive Christianity Missions Training Corps, a paramilitary religious cult operating out of the New Mexico desert, but also the cruelty of the cult's leader-her mother, Deborah.
In The Oracle's Daughter, Harrison Hill traces the fascinating beginnings and violent end of ACMTC, from its early days as an outgrowth of the hippie movement, through the conspiracy-theorist 1990s and into the present day. It follows Deborah, the group's founder and self-proclaimed oracle; Maura, one of its first members; and Sarah, Deborah's daughter, among the cult's primary victims.
With a propulsive, deeply researched narrative, The Oracle's Daughter illuminates the strange world of religious cults-and how more vulnerable we are to extremism than we might like to think.

Thanks to Scribner and Netgalley for this eARC.
Harrison Hill’s The Oracle’s Daughter: The Rise and Fall of an American Cult is a gripping work of narrative nonfiction that examines the corrosive power of belief, the fragility of family bonds, and the enduring allure of extremism in American religious life. It is a chilling chronicle of abuse and a thoughtful exploration of how ordinary people can be drawn into extraordinary darkness.
The Oracle’s Daughter tells the story of the Aggressive Christianity Missions Training Corps (ACMTC), a woman-led cult that operated out of the New Mexico desert. Hill frames the narrative around three women: Deborah Green, the self-proclaimed oracle and founder; Maura, one of the earliest adherents; and Sarah Green, Deborah’s daughter, whose eventual escape provides the book’s emotional anchor.
Hill writes with the pacing of a thriller while maintaining the rigor of investigative nonfiction. The opening scene—Sarah fleeing her mother’s compound in 1999—sets a tone of urgency and dread that carries through the book.
Deborah is not portrayed as a caricature of evil but as a deeply manipulative figure whose charisma and conviction ensnared followers. Sarah’s perspective, by contrast, embodies resilience and the painful process of reclaiming autonomy.
The cult’s roots in the countercultural movements of the 1960s highlight how idealism can curdle into authoritarianism. Hill situates ACMTC within a broader tradition of American religious extremism, making the story not just personal but cultural.
This book probes questions of power, obedience, and identity. It asks how devotion can be weaponized, how family ties can be exploited, and how communities fracture when ideology eclipses compassion.
Hill’s prose is clear, unsentimental, and deeply empathetic toward survivors. He avoids sensationalism, instead letting the facts and testimonies speak for themselves. This restraint makes the moments of cruelty and violence even more harrowing.
The Oracle’s Daughter succeeds as both true crime and social history. It is a story of survival, but also a warning about the seductive nature of certainty and the dangers of unchecked authority.
For readers interested in cult dynamics, religious history, or narratives of resilience, this book offers a compelling and sobering account.
If you’re drawn to nonfiction that blends psychological insight with cultural critique, this debut stands out as a powerful addition to the genre.
