Truckus maximus
(Book)

In a near-future world where the Roman Empire never fell, only two things matter: honor and the Game. "The Game" is Truckus Maximus, a competition where drivers race against one another - to the death. The best of the best is a young driver named Axl. The leader of Team Apollo, Axl drives hard and lives by a strict moral code. That code will be tested to its limits by the Caesar - the cunning ruler of the Roman Empire - and the Dominus, the absolute master of the Truckus Maximus games. The Dominus can change the rules of the game at will. Axl can't survive this race on his own. To do that, he'll have to embrace his team, including a defiant new racer named Piston. Will he learn that family is more important than honor or the Game? Or will he go down in flames?--adapted from publisher's description.
