Boom Town Boy — Lois Lenski

A boy and his grandpa hope to strike oil in drought-ridden Oklahoma 

It's hot in Oklahoma. There's no wind, the wells are dry, and the ground is dead. Orvie's family is doing everything they can to keep their farm going. If they miss a payment on the mortgage, the bank will take their home away, and they'll have nowhere else to go. Farming is tough, honest work, and it's no way to get rich. For years, Orvie's grandfather has sworn that there's oil under their land, and as soon as it starts bubbling up, they'll have more money than they know what to do with. But when the oil boom sweeps across Oklahoma, Orvie will find there are some problems that money can't solve.
 
This rich portrait of life during the Oklahoma oil boom provides a lovingly detailed look at a forgotten time in history.
