The Fourth Rome

Elite 26th-century commandos, the ARC Riders patrol time to protect all human history...

As the USSR crumbles, Russian hardliners jump from 1991 to AD 9, when their modern weapons can warp the course of the Roman Empire and create a world ruled by the Kremlin – using time technology that doesn't exist in the 20th century... or the 26th!

To solve the mystery, the Riders must split into teams separated by millennia. And while three Riders are trapped between the Roman legions and a blood-maddened barbarian horde, their comrades are at war on the Moscow streets. And fighting an inconceivable enemy.
