This title is part of Bug Club, the first whole-school reading programme that joins books with an online reading world to teach today's children to read. In this Lilac-level Trucktown book: Jack is on his way to the garage with a truckload of tyres for Ted. As Jack winds his way carefully through the rocky mountain pass an enormous boulder falls onto the road. Jack slams on his brakes and the tyres tumble off the truck and roll down the mountainside, blocking the entrance to the garage!
