Often funny, sometimes chilling and always thought-provoking, journalist Jon Ronson's Sunday Times bestseller The Men Who Stare at Goats is a story so unbelievable it has to be true.

In 1979 a secret unit was established by the most gifted minds within the US Army. Defying all known military practice - and indeed the laws of physics - they believed that a soldier could adopt a cloak of invisibility, pass cleanly through walls, and, perhaps most chillingly, kill goats just by staring at them.

They were the First Earth Battalion. And they really weren't joking. What's more, they're back and fighting George Bush's War on Terror.

Inspired the film starring George Clooney and Ewan McGregor.
