Read the excerpt from Roll of Thunder, Hear My Cry. When I reached the church steps, I looked back again. T. J. was still there, an indistinct blur blending into the gathering dusk, and I began to think that perhaps he would not go with the Simmses. But then the rude squawk of the truck's horn blasted the quiet evening, and T. J. turned his back on us and fled across the field.
