Fidelio's Automata, an Adventure in Alternate History (Steampunk)
A stolen invention threatens his dreams.
Fidelio Espinoza, a brilliant and idealistic young Cuban, arrives in early 1900's America with the goal of perfecting his automaton, a machine that will free humans from the dangerous, backbreaking work of mines and factories. Here he meets Hank, a cowboy turned Quaker who has vowed to atone for his sinful past. After a prototype of Fidelio's creation falls into the wrong hands, the two men join forces with Nikola Tesla to prevent this creation from being used in the service of oppression.
