As an Author and your wife...

If I die with anything unfinished and there's a call for such projects to be released to the public, whether that be for charity or to keep my family in a manner to which I'd like them to become accustomed...

DO IT!

With FULL permission. Publish EVERYTHING if it will help someone after I'm gone.

Let's face it, with my track record, there's going to be one or two (hundred) unfinished projects and if someone can benefit from them Please, have at it with a glad heart.
