Tis the season to be jolly--but Devin won't share his food for the school Christmas banquet, and he and Frankie forgot to read "A Christmas carol" for class. Then they meet someone with even less holiday spirit. Ebenezer Scrooge! The library zapper gates have transported the class misfits again, this time into Dickens's own Christmas classic. Frankie and Devin find themselves on a wacky, ghost-guided tour that just might turn around this humbug holiday.
