From the bestselling author of The Psychopath Test: A Journey Through the Madness Industry and So You’ve Been Publicly Shamed. A wide variety of extremist groups – Islamic fundamentalists, neo-Nazis – share the oddly similar belief that a tiny shadowy elite rule the world from a secret room. In Them, journalist Jon Ronson has joined the extremists to track down the fabled secret room.

As a journalist and a Jew, Ronson was often considered one of Them but he had no idea if their meetings actually took place. Was he just not invited? Them takes us across three continents and into the secret room. Along the way he meets Omar Bakri Mohammed, considered one of the most dangerous men in Great Britain, PR-savvy Ku Klux Klan Grand Wizard Thom Robb, and the survivors of Ruby Ridge. He is chased by men in dark glasses and unmasked as a Jew in the middle of a Jihad training camp. In the forests of northern California he even witnesses CEOs and leading politicians – like Dick Cheney and George Bush – undertake a bizarre owl ritual.

Ronson’s investigations, by turns creepy and comical, reveal some alarming things about the looking-glass world of us and them. Them is a deep and fascinating look at the lives and minds of extremists. Are the extremists onto something? Or is Jon Ronson becoming one of them?
