Frank Tavery was one of the children in Calla Bryn Sturgis. He is described as a beautiful, pre-pubescent child, with black hair, blue eyes and cheeks riddled with freckles.
He and his twin, Francine, were responsible for drawing up the map that Roland used to plan his attack against the Wolves. After setting up for the battle, he broke his ankle and had to be carried to the ditch with Roland, Eddie, Susannah and Jake, instead of the rice field with the other children. This would lead to the death of Ben Slightman Jr.
