The Worst of Times — James Lincoln Collier

When the Depression strikes America, throwing millions out of work, Petey Williamson's family seems safe. Hadn't the boss promised Petey's father that he'd always have a job? But during the Depression, promises cannot always be kept, and Petey finds his family sliding rapidly into poverty. And when Petey's much-admired cousin Steve starts working as a union organizer in the battle to improve conditions for workers, poverty turns into tragedy.
