Book excerpt: The Stig, Top Gear's tame racing driver, is off on another adventure, this time following his passion for speed and adrenaline to its natural conclusion - motorsport. Stig has disappeared into the world of racing, and it's your job to find him. Follow Stig as he roams from the stifling heat of the Dakar rally to the redneck heartland of a NASCAR track, or from the nightime drama or Le Mans to the mud-soaked stands of Silverstone for the British Grand Prix. Along the way you'll also find Clarkson, Hammond and May as they indulge in a spot of home-made motorhome racing or Roman rallying, middle-eastern style. The Where's Stig books have taken Top Gear fans by storm - and his latest voyage is the most action packed yet!
