Underworld Clash

Hercules and Theseus are trying to earn bragging rights of who is the best hero truck of all time. So they challenge each other to a race through the Underworld, the most dangerous place in the world. The obstacles and challenges they face are extra tough, and returning to Trolympia in one piece might be more important than winning. The ThunderTrucks early chapter book series has short chapters, bright art, additional Greek myth information, a glossary, and author and illustrator bios that will please both motorheads and mythology fans.
