What would be the inciting moment, climax, and resolution in Roll of Thunder, Hear My Cry? I think the climax is when the black and white people work together.
I would say that there were several examples of "inciting moments" in the novel. One comes when Cassie's mom loses her job as teacher. Another comes when Cassie is degraded by Mr. Barnett and Lillian Jean Simms during her visit to Strawberry. Yet another involves the family being attacked on the road returning with their goods. The climax begins in Chapter 11 when T. J. robs the Barnett store and concludes in the next chapter when the fire threatens to destroy the cotton fields. The resolution of the story comes when the black and white people of the area unite to put out the fire and save the cotton, afterward leaving the Logans where they had begun,
... free to run the red road, to wander the old forest, and sprawl lazily on the banks of the pond.
