Query: Unreadable!

I'm terribly disappointed with this book (KINDLE EDITION). It seemed good at the outset, but many sections suffer from missing words, typos, and garbled sentences, which make it unreadable. It looks like very sloppy work by a very poor typist... Shame on the publisher for not proof-reading the text, but also on Amazon for distributing such a defective book! I hope this will be corrected and that I shall be sent an upgraded version.
