Caldera relates a man's lifelong, dangerous, and heart-breaking pursuit to define, discover and preserve the meaning of "family" in the deadly and hostile desert environment of Arizona Territory.
Caldera continues his quest to find and determine the meaning of family within the violent times at the end of the Apache Wars. His quest is hampered by the arrival of an unknown half-brother, a Harvard educated tinderfoot with plans for a takeover of his (and Caldera’s) father’s enormous business empire.
