It is most interesting. Jim Butcher became one of my favorite authors as I was introduced to him back when he was already on Dreden vol #5.  I was able to quickly start the series and buy all his books as a result. I loved the Codex Alera novels.  Jim was putting out 2 books a year. He was hot.   The pace noticeably slowed down after Alera was over, but still 13-16 months for the next Dresden novel was still a good pace.  Then it started to falter.  It reminded me greatly of the pace drop off of Robert Jordan's Wheel of Time series.

Fortunately I never got into GoT ... but I sympathize with those readers.  Just as I sympathize for the wait for the 3rd book of P.R's Name of the Wind series.  I love these authors, I know they work hard and also need to enjoy life, but I miss their stories.  I miss the characters they have brought forth.

That being said, it was/is Jim's long absence that has opened my reading to new authors. I've bought over 100 books to read in these past 4 years and if you're interested in new reading I prepared a list for the wait. Believe it or not, I'd not known of these author's prior to 2013.  I'd always gone to the book store to buy hardback/paperback books, and since 2013 I've been using an Ipad because well, I have 100lb boxes of books in my basement just laying about and 4 bookshelves in the house all full of hardbacks for my favorite authors. (I have all of Jim's books in hardback collecting dust on one   )

Anyways, here for your enjoyment and if you like any of the books and haven't read some of the others in the category, then more than likely you'll really enjoy it as well.
