What plot climax is reached in this section of the book?

The biggest climax is if Stacey is alive or not. Papa, Mama, Hammer, and Cassie drive to Shokesville. It is very late so they sleep in the car. In the morning they head to the jail and the sheriff tells the deputy to go get the boy. The sheriff talks languidly as the family waits expectantly. He comments how the boys probably left their contracts but he has no sympathy for the landowners and the way they treat their workers.

A tall, gaunt figure comes down the hallway. It is Stacey, and he weakly falls into his parents’ arms.
