Harrison Hill is the author of The Oracle’s Daughter, out now from Scribner
“Terrifying, gripping, all true. I couldn’t put it down.” –Stephen King
“Excellent, told with rare sensitivity. Harrison Hill is an extremely skilled writer… The propulsive feel of a novel.” –The New York Times
On a cool fall night in 1999, twenty-six-year-old Sarah Green crept out of her house, retrieved a backpack from its hiding place, and ran for her life. She was escaping not just the Aggressive Christianity Missions Training Corps, a paramilitary religious cult in the New Mexico desert, but also the cruelty of the cult’s leader — her mother, Deborah. The Oracle’s Daughter is “a staggering achievement” (Leslie Jamison) that tells the shocking true story of ACMTC, while also investigating the history of cults and fringe religions across American history.
Harrison Hill grew up in Charlottesville, Virginia and lives in Brooklyn, New York. He received his MFA in nonfiction from Columbia University, where he also taught undergraduate writing. His journalism and essays have appeared in The Cut, GQ, Vogue, Travel + Leisure, AFAR, The Guardian, and The Threepenny Review. The Oracle’s Daughter is his first book.
PRAISE FOR THE ORACLE’S DAUGHTER
“Excellent ... told with rare sensitivity ... Hill is an extremely skilled writer, and his conscientious, measured reporting is a gift. He’s also a reliable guide who’s managed to create stunningly vivid scenes from the memories with which his subjects have trusted him ... The immediacy with which Hill portrays their conflicted longings gives the book the propulsive feel of a novel."
–The New York Times
"The twists and turns Hill follows throughout this true story are extraordinary … A story about the terror of losing the self — but it's also, gratifyingly, a story about finding the way back to it."
–NPR
“This true crime cult story opens with a scene straight from an action movie ... You come for the propulsive mother-daughter nightmare and the granular portrait of a survival in a closed world; you leave with a bracing sense of how mainstream the fringe can get."
–Oprah Daily, Best Books of Spring 2026
“An incredible new book that cast some sort of inexplicable spell over me demanding I follow its read-me now orders.”
–CrimeReads
“A staggering achievement, synthesizing rigorous reportage, incisive cultural analysis, and a deeply compassionate gaze into a propulsive and unforgettable narrative. The Oracle’s Daughter is as gripping as it is humane; I picked it up and barely put it down until I’d finished. I'll carry this story with me always.”
–Leslie Jamison, New York Times–bestselling author of The Empathy Exams
“Troubling, uplifting, heartbreaking, unforgettable — tapping into seminal issues of our increasingly divided nation — Harrison Hill has written a masterwork of narrative nonfiction. A must-read."
–Ron Suskind, Pulitzer Prize-winning author of A Hope in the Unseen
“With dogged research and rare access to victims and their stories, Harrison Hill has created a riveting portrait of one of the strangest American cults in recent memory. The Oracle’s Daughter offers compelling insights into the makings of religious cults and why their allure is increasing in our hyper-polarized, grievance-infused age.”
–Joby Warrick, author of Black Flags: The Rise of ISIS, winner of the 2016 Pulitzer Prize for General Nonfiction
“Harrison Hill's The Oracle’s Daughter does far more than delineate in vivid detail the alarming story of the Aggressive Christianity Mission Training Corps, surely one of the most frightening cults in modern religious history. Hill also provides essential cultural context, focusing not only on what happened involving that quasi-military group but also on how and why such a group can emerge. Anyone trying to understand religious cults should consider The Oracle’s Daughter required reading—it's that comprehensive and excellently written besides.”
–Jeff Guinn, author of Manson, The Road to Jonestown and Waco
“Beautifully told, un-put-downable, and urgently necessary, Hill offers a novelesque account of a cult that pushes beyond familiar narratives, asking us to consider just how far we truly are from the most radical edges of American life.”
–Heather Radke, author of Butts: A Backstory
“The Oracle’s Daughter is both an intimate portrait of one insular group and a revealing exploration of the broader cult history woven through America. If you've ever wondered how a person could fall prey to a high-control group, or what it takes to get out, this book is essential reading.”
–Rachel Monroe, author of Savage Appetites
“A moving, true and complex family storythat sheds light on individual struggles for freedom. I couldn't put it down. Intimate and expansive, it is both disturbing and hopeful.
–Suzanne Joinson, author of The Museum of Lost and Fragile Things
