It's simple to get The Book of Pook as an Audiobook! (Over 13 hours of human being narration - FAR more advanced than the equipment produced TTS on this web site!)
We also suggest looking into Pook's other guide, "The Pook Manifesto" Audiobook (Over 15 hours of individual narration). It really is much longer, contains more some ideas, and it is a lot of fun to be controlled by. If you prefer the Book of Pook, you certainly will love that one.
