A lost world has been found again...and no one is getting out alive.
1863, a group of mercenaries in Montana come upon the remains of a once-thriving mining town. They soon discover that the destruction was not wrought by human hands, but by creatures long forgotten. William Meikle delivers a classic Lost World story with just the right touch of Horror and Western. You'll be on the edge of your seat as you descend into The Valley.
