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.
