All the Earth, Thrown to the Sky — Joe R. Lansdale

Jack Catcher's parents are dead -- his mom died of sickness and his dad of a broken heart -- and he has to get out of Oklahoma, where dust storms have killed everything green, hopeful, or alive. When former classmate Jane and her little brother Tony show up in his yard with plans to steal a dead neighbor's car and make a break for Texas, Jack doesn't need much convincing. But a run-in with one of the era's most notorious gangsters puts a crimp in Jane's plan, and soon the three kids are hitching the rails among hoboes, gangsters, and con men, racing to warn a carnival wrestler turned bank robber of the danger he faces and, in the process, find a new home for themselves. This road trip adventure from the legendary Joe R. Lansdale is a thrilling and colorful ride through Depression-era America.
