Query: Poorly written and even poorly edited...

Literally every sentence of this book is filled with grammatical and spelling errors. It does get quite annoying at times to read through the text.The illustrations and diagrams are of poor quality. I bought this book as the author is quite renowned in the field of stress stesting. I think it would have been a great book if only someone had taken the time to proof read and edit the text before publishing it.
