Long time king fan. Have read many, many of his books. Just started the Dark Tower series. Read the first 3 books in less than a month. Totally addicted now. Just started the 4th W&G and I heard the latest book (wind through the keyhole) is considered technically 4.5. I wanted to see everyone's thought on the reading order. Should I go W&G to Wolves or W&G to Keyhole and then Wolves?
