It is brilliant but god damn he needs an editor who will stand up to him. I have stagnated on book 2 after about 5 chapters of tangential world building for some future part of the story. By the time I get there, I won't remember those 5 chapters.
Wait for it. It's coming. A jump into another city somewhere with no explanation and a whole bunch of new characters you haven't been introduced to. Like a story within a story within a story. I thought my toddler must have been playing with my ebook reader and skipped me to the next book.
