Which makes it weird (not sure if weird is the right word to use). I bought the paperback version of Book 4: Duel Nature on Amazon aka a used copy of it and it came in the mail and it had the Half Price Book price sticker on it from Columbus I think yet I’ve looked on Half Price Book website for two years (on and off again) and never once found any books from the Demon Accords series. By looked on Half Price Books website I searched it up to see if I can find a copy but no such luck.
