This is a fun book to read and many take it for being a true story (the guy who introduced is one who believe every word s true), but it is not, it is a novel, fiction. Some don't believe it but just read the copy right notice by the end. It is also a free book in digital form and you can share it as much as you want as long as you have not altered it. If you want a printed copy of cause you need to pay or lend from some one who has.
