Nothing ever happens in Toby's small Texas town. Nothing much until this summer that's full of big changes.
It's tough for Toby when his mother leaves home to become a country singer. And Toby takes it hard when his best friend Cal's older brother goes off to fight in Vietnam. But now their sleepy town is about to get an even bigger jolt with the arrival of Zachary Beaver, billed as the fattest boy in the world. Toby is in for a summer unlike any other, a summer sure to change his life.
