Apr 2026: fake news about completion
Aug 2026: Martin depressed and struggling.
Okay not much progress since 2023. Around 2024-2025 that when he hit a snag. Although looking at this timeline, this do like good progress for someone so old. I assume the rest 500-600 part of the book is the final part of Winds so he need to tied them together. Oh and my guess is the secondary pov character are finished at least. And by finish… they’re likely dead. Considering he start ddompotijg around 2025 and 2026 was a bad year… it seem he lost it
The comments made me realize how many people given up on it and they want to man to lay down his pen or pass it over
“This year has been… stressful, to say the least. So much has been happening, it’s been overwhelming. Some great things, exciting things. Dreams coming true. But there have been nightmares too. “ : this was his last blog post. There were talks about the bad things. But they’re also great things like the award ceremony for KOTSK s1. Mad king play is also one onvisoul. Maybe the game? Maybe more thing in development?
We know from Parker he working on Dunk and Egg.
