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?
