Zara lives for bike rides with her friends--so when her shiny, brand-new bike goes missing from the park one day, she's crushed. After her parents insist she earn the money for another one herself, Zara's determined to start a business. But what kind? A lemonade stand? Not profitable enough. Selling painted rocks? Not enough customers.

Zara's starting to get discouraged when she and her friend Naomi finally come up with the perfect idea: The Treasure Wagon, a roving garage sale that unloads knickknacks from the Saleem family basement and makes money all at once! But when a mix-up gets Zara in hot water again, will she have to give up everything she's earned toward her new bike?
