Book 5 is finished!
From Brandon Sanderson:
Finished the last interlude today at 5:21. That is a wrap: Wind and Truth, Book five of the Stormlight Archive, is finished. Tomorrow morning, I'll hand it off to the proofreading and copyediting team. 491k words. The first file I have in my folder for this was dated March 2021, though active writing started about a year after that. So two years and a few months spent working on this full time, with another year of working on the outline. Feeling great about this final version! See you all December 6th. The book, finally, is DONE.
