Hitch a ride with 11-year-old Hazmat and her Dad in their 18-wheeler, Leonardo, for a feel-good road trip across America that keeps on trucking!

Life on the road with Daddy is as good as gets for Hazmat. Together, they've been taking jobs and crisscrossing the US for years. Now Daddy's talking about putting down roots—somewhere Hazmat can go to a real school and make friends. Somewhere Daddy doesn't have to mail-order textbooks that talk about "nature's promise to all women."

And while everything just keeps changing, sometimes in ways she can't control, Hazmat isn't ready to give up the freedom of long-distance hauling. Sure the road is filled with surprises, from plane crashes and robo trucks to runaway hitchhikers and abandoned babies, but that all makes for great stories! So Hazmat hatches a plan to make sure Daddy's dream never becomes a reality. Because there's only one place Hazmat belongs: in the navigator's seat, right next to Daddy, with the whole country flying by like a crazy quilt and each day different from the last.
