The Accelerators, Volume 1: Time Games

A band of reluctant time travelers find themselves trapped in a future where time travel has left the world in ruins. There, they become prisoners of the Time Games, a gladiator arena that steals people from different points in history and forces them to fight for the pleasure of the crowd. Our heroes struggle to survive the Games and escape from this nightmarish apocalypse, but with no way back, the future may be their only hope.
