The instructions were simple, but the results were extraordinary. 'You are invited to anonymously contribute a secret to a group art project. Your secret can be a regret, fear, betrayal, desire, confession or childhood humiliation.

Reveal anything - as long as it is true and you have never shared it with anyone before. Be brief. Be legible.

Be creative.' It all began with an idea Frank Warren had for a community art project. He handed out postcards, asking people to write down a secret and post it to him, anonymously. The response was overwhelming.

In under a year, Frank had over 10,000 cards which he posted on the website. The confessions were thought-provoking, funny and weird, touching on every aspect of human experience and revealing much about the state of modern life, and catapulting PostSecret to the status of global phenomenon. Superbly illustrated throughout, this book is a great conversation piece, fascinating to flick through, and almost unputdownable once you have.
