Query: Book 6 of Dark Tower Series by Stephen King

I have been racing through this series and loving it. Can't believe I waited this long, however it gave me the opportunity to read them all back to back. King is genius and doesn't disappoint in this book. I'm still very in love with these characters and their integration into my own life-time. This series of books beats the heck out of LOTR or HP, it's the average Joe's fantasy fiction that took King over 3 decades to pen.
