Just Like Brothers, by Elizabeth Baguley

Near the woods live a little boy and his mother. The mother warns her son to watch out for wolves, but he doesn't listen. Instead he chases rabbits. And in the woods live a wolf cub and his mother. The wolf warns her son to watch out for people, but he doesn't listen. Instead he chases rabbits. What will happen when the boy and the cub cross paths in the forest?
