Query: Bad Kindle Version

This book is is good, the content it self is very acurate and usable. The major issue is the kindle version has a great deal of text errors. In some cases many errors on each page. Whole paragraphs are out of place in some chapters. I would not purchase the Kindle Version of this book. If you want to purchase go with the old fashion paperback.
