Five years. That's how long Coyote and her dad, Rodeo, have lived on the road in an old school bus, crisscrossing the nation. It's also how long ago Coyote lost her mom and two sisters in a car crash. Coyote hasn't been home in all that time. But when she learns that the park in her old neighborhood is being demolished-the very same park where she, her mom, and her sisters buried a treasured memory box-she devises an elaborate plan to get her dad to drive 3, 600 miles back to Washington State . . . without him realizing it.
