Borrowed the book "au gratis" on my Kindle fire.
I have been playing for over twenty years....but took about a 15 year break in the middle.

Now older, wiser, wider, bald, a dad, and a mortgage in tow...I find myself with the time and desire to play again. Back in the 80's and early 90's there was no real way to improve other than to put time in. No internet means you have no idea (based on reviews) of which books are better or worse. As such, we all just played. I was never that great, just enjoyed playing.
Jump to the past October when I started playing again. Now with all this information at my fingertips (amazon with book reviews, AZB with advice...and a new awareness of what cues really cost at the high end) I decided to improve my game. Winning a tournament would be a blast, but for now...if I can just be better than everyone else I play with...well that'll be all right.
I took 3 lessons with a BCA instructor...Each one was about a month apart. After each lesson I was so noticeably better is was crazy. But after a week of the lesson, without any actual natural talent, I would fall back into old habits. I couldn't remember what fundamentals I needed to improve on. I told the instructor I wanted to bring a notebook as I realize what was missing was a hard adherence to fundamentals (pre shot routine, stance, grip, stroke, aiming...).
The best video to date I have seen on these fundamentals was Mike Sigel's Perfect Pool set. It really sounded like the lesson. But was a bit fluffy with banter. That guy with Mike was like a circus monkey dancing around tirelessly and interrupting Mike every two minutes. I don't think Mike Sigel could have done it on his own as the other guy helped keep the video on a specific track, but he could have toned it down a bit. I thought he was gonna punch his fist into the pool table and try to sell me the Slap Chop.
So...this book by Lee Brett is near perfect in my opinion. I think it makes some basic assumptions about your game. But it's well done. The way it's written is, to me, very clean, clear, and concise. It might be missing a few things, but that can always be expanded upon at a later edition.
My review for this book is simple. I borrowed it for free on my Kindle, and then paid 30.00 for the actual book. I'm a pretty cheap guy, so wanting to actually buy this book says a lot.
Lee? Well done. I think the book is indeed a bit short for the 30.00 price tag...maybe a 20.00 price tag might actually sell more copies. But one could argue that the book is just as informative as a 300 page book, just doesn't have all the banter and stories that other books have. It's like a plate of vegetables...it might not be as good as a nice cheeseburger...but it has everything you need and nothing you don't.
I'm eagerly awaiting the DVD. If it's as good as the book it will be the best thing to come along that I am aware of. But with many instructional DVDs the editing is so poorly done that it sometimes detracts from the actual content. Let's keep our fingers crossed.
So...the book? Just get it. Borrow it for free if you can. $29.99 is a lot of money for a small book. Oh...if I had one complaint? ...Even books from 200 years ago have page numbers. I know it seems irrelevant, but I would like to see page numbers.
Other than that, fantastic. Wish you lived close and gave cheap lessons. lol
