I don't know a lot about writing but I do know enough about Raff to believe that there are probably enough stories and photos of and about Paul to make a pretty darn good book (maybe called Raff or Blue Skies, or whatever) about him, and I'd be willing to bet that it would sell enough copies to enable the proceeds to be able to be used for Alexa's education or whatever worthy cause might be appropriate.
Again, I'm not a writer, and I only knew Paul for a few years, but I know I'd buy a book about him.
Someone with great writing ability should seriously give that some thought. I'm sure there are thousands of people who would willingly contribute their stories and experiences. And I think the content would be something that could potentially sell lots of copies.
