But there are many threads that are very stale now. Where is Cowl and Kumori? What's the deal with the Elaine? How about the Black Council? We've seen the Denarians but what about the rest of Hell? The attack on Archangel, the attack on Arctis Tor, the origins of a bunch of species, the history with Merlin (and Mab), the involvement of humans with the supernatural (like the FBI getting belts), and Harry's mother's own history are all things that have been left hanging for a LONG time. Not to mention Harry talking with the actual White Council, not just Eb or Ramirez. What have they been up to? What's the Gatekeeper's position on recent events and what is his story? etc. etc.
I understand the sentiment; however, maybe some of these things are just what happened, and that's the way it is. The attack on Archangel could just have been an overwelling number of vampires attacking when it was least expected. Where/when would Harry talk with the (as the post said) actual White Council vs. Eb or Ramirez? Harry doesn't like the council, and the council doesn't like Harry; I don't think either would go out of their way to purposefully interact. Besides, we have several short shorties and in-book interactions with Wardens and the greater Council.
However, I completely agree that we need more information on Harry's mom and the Gatekeeper (would take a book about either of these characters).
