Jon Ronson is fascinated by madness, extraordinary behaviour and the human mind. He has spent his life investigating crazy events, following fascinating people and unearthing unusual stories. Collected here from various sources (including the Guardian and GQ America) are the best of his adventures.

Always intrigued by our ability to believe the unbelievable, Jon meets the man preparing to welcome the aliens to earth, the woman trying to build a fully-conscious robotic replica of the love of her life and the Deal or No Deal contestants with a foolproof system to beat the Banker. Jon realizes that it's possible for our madness to be a force for good when he meets America's real-life superheroes or a force for evil when he meets the Reverend 'Death' George Exoo, who has dubiously assisted in more than a hundred mercy killings. He goes to a UFO convention in the Nevada desert with Robbie Williams, asks Insane Clown Posse (who are possibly America's nastiest rappers) whether it's true they've actually been evangelical Christians all along and rummages through the extensive archives of Stanley Kubrick.

Frequently hilarious, sometimes disturbing, always entertaining, these compelling encounters with people on the edge of madness will have you wondering just what we're capable of.
