A Parade of Horribles (hardcover) Matt Dinniman

As chaos and mass panic spread outside the dungeon in the wake of Faction Wars, Carl and Donut find themselves on the tenth floor, where they’re forced to compete in a surprisingly normal set of tasks. Well, normal for the dungeon.

Races. Get from point A to point B, and don’t come in last. After each race, they pick an upgrade for their vehicle and the track gets more challenging. It all seems a little too normal, a little too simple.
