According to the article I read this morning, Robert left a detailed outline and a good portion of the final book written, and arranged for a ghost writer to finish it. So even though he can’t, we will see the final book in print.
So don’t despair just yet. Though I knew his publisher letting him write those Conan series before finishing Wheel was a bad idea.
Anyway, it’s a sad loss, but his work will live on, and hopefully we can get our paws on that final book soon.
