The Black Iron Empire — James E. Wisher

Transported by unknown magic, Joran and his companions find themselves in a vast, lifeless wasteland. Struggling to survive in the hellish landscape, they search for any clue to a way back home. Unknown to them, a familiar foe is on a different quest. Samaritan seeks the location of an ancient weapon, something powerful enough to destroy the Tiberian Empire, The Church of The One God, and everyone he hates. Can Joran stop Samaritan before it's too late and hopefully find a way home at the same time? The race is on and Joran must win if he doesn't want everything he loves to be destroyed.
