Jon Ronson writes books best described as satirical journalism. Best known for his piece on a proposed New Age Army later made into the all-star film The Men Who Stare at Goats. I won't link to the film (we have it), because the book from which it is taken, Them: Adventures with Extremists, is much better.
Ronson is also well-known for interviewing the paranoid and the conspiracy theorists. In the process, he subtly deconstructs the subjects' own psychological problems without ever overtly saying anything (he's British after all).
His journalistic style is low-key and British. Ronson generally asks his odd subjects dead-pan questions and gets them to reveal much about their worldview.
Recommended for fans of non-fiction writing, journalism, and studying the art of interviewing.
