What Ethan needs is a quiet place to lay up after his last job settling a dispute between ranchers. What he doesn't need is entanglements: like making promises to a boy and an Apache chief, like making enemies of Rufe Harris and his outfit, and like falling in love with a woman who happens to be a nun.

Least of Brothers is the tale of a young man, orphaned as a child and raised by an Apache scout, who gains a reputation throughout the southwest as a top gunman and tracker. Respected by lawmen and feared by his foes, only a few know Ethan's real identity, to everyone else he is the famous Apache Jack. After his last job Ethan has saved enough money to leave behind the outlaw trail and head west to live out his dream on the land he has purchased. Then he meets three people who will forever change his life.
