What if you were thrown into a foreign society, never to see home again? What would you do, and could you survive?

Joe Colsco boarded a flight from San Francisco to Chicago to attend a national chemistry meeting. He would never set foot on Earth again.

On planet Anyar, Joe is found unconscious on a beach of a large island inhabited by humans where the level of technology is similar to Earth circa 1700. He awakes amid strangers speaking an unintelligible language and struggles to accept losing his previous life and finding a place in a society with different customs, needing a way to support himself and not knowing a single soul. His worry about finding a place is assuaged when he finds ways to apply his knowledge of chemistry - as long as he is circumspect in introducing new knowledge not too far in advance of the planet's technology and being labelled a demon.

As he adjusts, Joe finds that he has be dropped into a developing clash between the people who cared for him, and for whom he develops an affinity, and a military power from elsewhere on the planet - a power with designs on conquest. Unaware, Joseph Colsco has been poured into a crucible where time and trials will transform him in ways he could never have imagined.
