Read the excerpt from "Dwaina Brooks.”Dwaina's sisters, Stephanie, sixteen, and Crystal, nine, already had aprons tied around their waists. Dwaina turned on the radio, and they all formed an assembly line and dug in. Gail threw chicken into three skillets and got them all going at once. Dwaina slapped meat on open slices of bread and covered them with mayo. Crystal wrapped sandwiches and stuffed sacks. Dwaina looked on proudly as the corner of the kitchen began to fill up with sacks. It looked like a lot of meals.
