The Fourth of July means three things: fireworks, family, and car races! It's a big race for Denny, and this year, Zoë is finally old enough to compete in the Kids' Kart Challenge. Enzo knows Zoë has been practicing, and he's seen how fast she can go. He is sure that Zoë will win first place! But when one of the boys at the track says that girls aren't fast drivers, Zoë gets nervous and backs out of the race. And when Zoë loses heart, so does Denny. It's up to Enzo to help his family regain their confidence to compete. Because Enzo knows that the fun isn't in winning, it's in feeling the wind in your fur as you race around the track. Go, Enzo! New York Times bestselling author of The Art of Racing in the Rain Garth Stein captures the excitement of the Fourth of July and the thrill of a good race in this adventure-filled addition to the beloved Enzo series.
