Adventure is calling... and this time it's riding on eighteen wheels! When Marvin the Mole, his courageous cousin Maxie, and inventive cousin Marcie are invited to join America's Great Route 66 Convoy Challenge, they set off on the journey of a lifetime. Driving Convoy #66 from Chicago to Los Angeles, they travel historic Route 66, meet unforgettable new friends, and discover remarkable places most travelers never notice. But along the way, Marvin uncovers a mystery hidden deep within the history of the Mother Road. Why have certain landmarks vanished from guidebooks? What is the meaning of the strange road-circle symbol appearing in forgotten places? And what is the secret of the legendary "Place Where the Road Listens" that travelers have searched for across generations? Filled with colorful characters, big-rig adventures, Route 66 history, humor, friendship, and heart, Marvin the Mole: Convoy Across America is a journey about more than reaching a destination. It's about discovering the stories, kindness, and connections that make every road worth traveling. Because sometimes the greatest treasure isn't found at the end of the road... It's found in the travelers beside you.
