Yeah! He's one of my favorites, and years ago the one I read the most... and he has many more works, some unknown like this one that I've only recently discovered. I think he's always been a visionary, who knew more than just telling fictional stories. About this one, I found it on Italian but not easy, actually the Wikipedia page about the novel is much more complete in Spanish and very short in English, don't know why.... anyway hope you can find it or if I see it I will let you know.
