I would prefer a book on the backstory of Susannah. I read all the books while waiting to start my job post law school. Agree though would love to see a full power Roland. Spoiler Book 6 was so fucking bad. I just kept waiting and waiting for it to get good. Then Book 7 with the Crimson King just being erased was so anti-climatic. I was thankful just to be done after reading 5-7.
