The Story

Two lifelong friends. One elk trail. A world that shouldn't exist.

Deep in Colorado's San Juan Mountains, two lifelong friends follow an elk trail into the unknown, and step into something that doesn't belong to this world. While they fight to survive in a savage, prehistoric land ruled by ancient predators and a brutal natural order, a desperate search ignites back home. In the mountains, weather turns deadly. Every clue leads nowhere. And something is hunting them.

What follows is a fight for survival and a desperate search to find a way back home. Lost in Colorado is a sci-fi portal survival thriller for adult and young adult readers alike, the first book of a trilogy, and the work of twenty-five years.
