Who was reading: A tween-age girl with elaborate rubberized headband.
Product Description (via Amazon ): "One minute Roger is his usual nasty self, the next he's carrying Beebe's books and opening the door for Ms. Kristal. Can Doug find out what's going on?"
Unlike Doug, this "reader" may never find out. . . She was using the book as a hard-surface upon which to complete a word-search.
Bonus points: Library Book!
