Thrown out of his own universe by unknown cosmic forces, a man finds himself marooned in an eerily familiar, but strange world.  It is like he was tossed three hundred years into his own past.

With no way to return, he looks at his new home with foreboding.  If its history matches his own, he knows that within fifty years tens of millions will die in the most horrific wars of the human race.  Can he - should he- try to stop it?
