NEW YORK (AP) — With apologies to Nathaniel Hawthorne and admirers of “The Scarlet Letter,” Dav Pilkey has a shameless name for the next installment of his multi-million selling “Dog Man” children's books series about a canine superhero: “Dog Man: The Scarlet Shedder," to be published March 19. Woof. “Dog Man started out as a character I created when I was in second grade, but the series has evolved into a love letter to my parents," Pilkey said in a statement released Thursday by Scholastic.
