The Holocaust Engine

It begins with disease.

A brain-rotting virus, which leaves its victims disoriented and hyper-violent, rages out of Cuba into the Florida Keys. The bewildered government destroys the mainland bridge and places the islands under quarantine. Inside this cordon, the population descends into chaos, as rival factions battle over dwindling resources, buildings become fortresses, boats lash together as defensible islands, and whole neighborhoods wall off into armed camps.

As order slips beyond any chance of recovery, hopelessness reigns. But not everyone accepts this fate.
