Outlanders, The Lost Earth Saga #1: Hellbound Fury by James Axler

Kane and his companions find themselves catapulted into an alternate reality, a parallel universe where the course of events in history is dramatically different. What hasn’t changed, however, is the tyranny wrought by the Archons on mankind, this time with human “allies”. Book one in the new “Lost Earth Saga”, a trilogy that chronicles the heroes’ paths through three very different alternate realities, where the struggle against the evil Archons goes on.
