In which chapter of The Wednesday Wars by Gary Schmidt does Holling's sister almost get hit by a bus?

In the chapter entitled "January," Holling is walking home, about to be attacked by Doug Swieteck's brother and other boys holding snowballs, when he sees the school bus gliding into the intersection and going through a red light. He sees his sister in the middle of the intersection; she is walking with a scarf over her "southern California hair" to keep it dry. Holling races to push his sister out of the way of the bus into a snowbank, and he is hit by the bus's rear bumper in the buttocks. Mrs. Baker drives him to the hospital to get an X-ray, and his sister thanks him for saving her life. He is sore, but he is left without a serious injury and is featured in the town paper as a hero.
