Second Chance by Galand Nuchols
Josh and Leroy are friends despite their differences. They face a world of depression, segregation, drought, and prohibition. Josh, the main target of the town bully, uses the boy's Achilles heel to even the score. Leroy hates the father he has never seen, but he must make life changing decisions when the man returns to be a part of Leroy and his mother's lives.
They help a mutual friend, George, and his family walk a tightrope, as they deal with their white neighbor, who is determined to get rid of them. Together the three friends bring a small measure of justice to their challenging world, as they each experience a second chance.
