"A deep dive into the world of flat Earth conspiracy theorists . . . that brilliantly reveals how people fall into illogical beliefs, reject reason, destroy relationships, and connect with a broad range of conspiracy theories in the social media age. Beautiful, probing, and often empathetic . . . An insightful, human look at what fuels conspiracy theories."
--Science

"This provocative book is sure to inspire debate about conspiracy theories as well as how citizens of a fractured world can learn to overcome their fear of radical planetary change. A timely and disturbing study of flawed, dangerous thinking."
--Kirkus Reviews

"Insightful and surprisingly empathetic . . . an illuminating take on a much scrutinized subject."
--Publishers Weekly

"An illuminating study that locates the common human psychological impulses behind conspiracy culture."
--Library Journal

"In lively prose, Weill untangles the most complicated webs, revealing the real people who believe the unbelievable."
--Booklist

"Even-handed... perfectly encapsulates disturbing implications of conspiracy theorists and their beliefs."
--Minneapolis Star-Tribune

"The book is well-researched and makes for quick and entertaining, if disturbing, reading."
--Ars Technica

"An inquisitive, empathetic, deeply reported, and disturbingly funny tour through the furthest reaches of the most fringe possible conspiracy community. While Weill's subjects frequently risk falling off the edge of their own self-created map of the known universe, she follows them deftly to the brink, showing what their delusional explorations can teach us about belief, community, and the long history of pseudoscience around (sorry!) the world."
--Anna Merlan, author of Republic of Lies

"In this delightful deep dive into flat earth culture past and present, taking in YouTube recommendation algorithms, amateur rocketry, and a rat's nest of conspiracy theories, Kelly Weill explains why, after several millennia of setbacks, the idea that the earth is flat is burgeoning once again."
--Michael Strevens, author of The Knowledge Machine

"Weill's elegant writing, informed by both historical research and deep-delving reporting, offers a complex and vivid portrait of a conspiracy community that serves as a metonym for this moment--when so many of us are in dispute about the very nature of reality. An essential and enjoyable read."
--Talia Lavin, author of Culture Warlords

"Kelly Weill is one of the best observers of the fringes of modern American life, making her the perfect chronicler of the Flat Earth movement. Her deep reporting and gift for storytelling make Off The Edge a gripping read-- but what sets Weill apart is her ability to cover her subjects with great empathy, all without losing sight of the enormous damage and personal consequences of their actions."
--Charlie Warzel, co-author of Out of Office
