I am only partially through the book and I will be a critic. Since I downloaded this book I was nearly late for work. I only got a few hours of sleep and have been oiling my small collection of defensive tools. Yes, if you have the digital version there appears to be spacing errors. Having read MANY digital books, to include college texts, when the printed word is sent to a Kindle the spacing is ALWAYS messed up. Go download the Army's Sniper manual, you will believe Equinox is letter perfect. Poor Man's James Bond? DON'T DOWNLOAD THAT!!! Waste of money on digital. Last but not least, if you haven't published a book or an article hold your critiques. There will always be the trolls that will complain about a book or a youtube video about amateur radio but have NEVER tried it themselves. Mr. Dennis, I haven't finished the book but e-mail me when the sequel or spin off comes out.
