A story that invites participation and promotes letter recognition. When Little x disappears from Charley's Alphabet, the rest of the letters search for him, finding him in the castle of Master M. To their surprise, he does not want to be rescued, because he is useful there unlike at home, where Charley seldom uses him. When Master M awakes and threatens to use the letters in soup, Little x comes to the rescue and they all return home safely. There, Charley helps his dad decorate a birthday cake for his mother, and he uses Little x four times-because it is the only letter that stands for kisses. As in Alphabet Adventure (Scholastic, 2001), children will work on a skill necessary to begin reading as they enjoy the story and the bright, three-dimensional-looking digital illustrations filled with detail.
