Dec.1 (GMM) A revised version of Lewis Hamilton's 2007 autobiography 'My Story' has hit the book stores.

'My Story, Special Celebration Edition', at a cost of $30, includes an extra chapter dealing with the 2008 formula one season, from which the McLaren driver emerged as the sport's youngest ever world champion.

"I am far too young to have a full autobiography," the British driver writes in the new edition, apparently addressing the criticism of his original $2m book deal that was inked not six months into his F1 career last year.

The updated hardcover version is bigger, includes more photos and additional written material at the beginning and the end.
