Query: Shoddy Kindle version

Interesting book on Jaco, but this Kindle version has an appalling number of typos. There seems to be no quality control whatsoever. In addition to dozens of dropped apostrophes, periods and other punctuation, there are misspellings and wrong words. In fact, in one place, "Jaco" is rendered as "face." This is my first Kindle book, and I like the format, but this version is a disaster.
