@ilumium As far as I've gathered from the vibe on the internet, people have been waiting for the last book(s) for more than a decade.

Do with that information what you wish.

I would actually almost advise to keep this high note in your heart and stay away from the later seasons of the TV show. Because the TV show gets so bad, it will manage to ruin it.

Find whatever head canon you like best and treat it like the end of the story?
