I have no issues waiting further. There are too many great books to read or reread to let a few weeks (or months) really affect me.
That being said, Joe is one of only maybe two or three authors where I have read all of their works. So if there is an author where I will devour their work as soon as it becomes available, it is Joe. I am really looking forward to Red Country and have little doubt it will be as great as the previous 5.
