The Caldera Trilogy

What is the meaning of family and what dangers does a quest to discover that meaning bring?Down on his luck Mountain Man Bull McKenzie discovers a treasure in the rugged Superstition Mountains of Arizona. Later, as one of the richest and most powerful men in Arizona Territory, he fathers a son by one of his prostitutes. The boy, named Caldera, means nothing to McKenzie. He hands off Caldera to a Pima warrior/farmer who comes to love the boy and who raises him as his own son.
Caldera is torn between the love he has from his surrogate father and the indifference of his blood father. Caldera's quest to find the meaning of family becomes a deadly, twisting journey as he becomes: a free-spirited kid, Confederate Army scout, capable cowhand, the falsely-accused murderer of his wife and unborn child, and a legendary madman on a vendetta ride. His quest seemingly comes to a conclusion as he finds war, betrayal and perhaps love in Cuba as a behind the lines spy for Teddy Roosevelt's Rough Riders.
