It's 1966, and sixth grade offers nothing but challenges for Alan Cower. Since his father's death, Alan feels unmoored, with only his favorite Greek myth-the labors of the legendary Hercules-to keep him company. That is, until Cyril, his kindhearted bus driver, takes Alan under his wing.

While Alan struggles with a budding crush on his classmate Julie and bullies who seem determined to make his life miserable, Cyril guides him through life lessons using myths-a topic they both love. The more Alan discovers from the stories, the more confidence he gains. With each bus route traveled and page turned, Alan has a chance to embrace his own courage. Will he take it?
