Weird question, but I'm always thinking about Terry Pratchett and how he had his computers and hard drives containing unfinished works steamrolled when he died.
What would you want done with your unfinished works? And/or have you ever considered leaving instructions for that sort of thing?
I don't care, I'll be dead.
... Maybe I'll construct an elaborate worldwide hide-and-go-seek game to find the final book, ala Cicada 3301. At the end of which will be either my masterpiece, OR! ... Nothing...
