This 18,000-word novella is the third story to feature my enigmatic hero, known as the Old Man in "Helping Them Take the Old Man Down" and as the Big Man or "the man himself" in "Clockworks." In "Unearthed," our rather youthful Old Man, referred to as Little Boss, is sent to his father's mine in a forgotten South American country in response to a cry for help. Disaster has struck the miners in the form of mysterious delusions, and a journey underground with the sole English speaker, a young Mohawk woman, leads our protagonists to the bizarre source of the affliction . . . and provides them with a life-changing mission. The three stories are best read in the order in which they've been published in Asimov's Science Fiction--that is, out of chronological order. "Helping Them Take the Old Man Down" takes place in 2001-2002, and should be read first. "Clockworks" takes place in 1962. "Unearthed" takes readers as far back as I plan to go, 1925. Two more stories, both sequels to the original tale, are in the works. The earlier stories are available, bundled together as a single e-book, via both Amazon and Barnes & Noble.
