My Autosaurus Will Win! (Geronimo Stilton Cavemice #10)

For cavemouse Geronimo Stiltonoot, life is one prehistoric problem after another! Geronimo Stiltonoot is competing in a race to Boulder Bay and back! It's dangerous, but it will supply the village cheese maker with rare hot lava peppers, and there's a big prize for the winner. Unfortunately, Geronimo has a lazy, slow, city autosaurus (the cavemice mode of transportation). Can he reach the finish line without going extinct on the way?
