Hang on to the wheel for the first of three adventures from a dynamic mother-daughter pair: beloved author Shirley Hughes and talented illustrator Clara Vulliamy.

Digby O’Day and Percy are best friends. This daring canine duo can find adventure anywhere — even entering an All-Day Race! Digby is sure he can win, especially with Percy as his co-driver. But when the race starts and Digby and Percy are quickly left in the dust, it seems like they don’t stand a chance. They meet peril after peril: a car that breaks down (and slides back to the edge of a cliff!), a near miss with an oncoming train, and worst of all, Digby’s archenemy, Lou Ella, who is also in the race and will stop at nothing to win. In a day full of twists, turns, thrills, and surprises, anything can happen. Who will come out ahead? And will Lou Ella get her comeuppance?
