First, I find it rather disturbing from an intellectual stand point that there would be 64 five star reviews, most of which were posted before the book was even released, the day of, or a few days after. This is very fishy and I really hope Dave Camarillo had nothing to do with it. With that being said, I assume all the reviews are the same person, people who train with Dave, people who helped write/publish the book, or others somehow involved with Dave or the publication in one way or another.
This book is horrible. It is quite easily one of the worst jiu jitsu books ever written. The book can best be summed up as: always look for the submission. That's good advice, especially against better opposition when a lot of submissions occur in transition or scrambles. Other than that overarching point, the majority of the book is just different arm bar set ups. It doesn't go over a lot of submissions or how to even get to certain positions. It usually starts off with Dave already in an advantageous position (like side control) and proceeds to show how to do an armbar variation. Of course, for a lot of people buying the book, the problem is they can't even get to that position.
Other than being one dimensional (arm bars mostly), the books major flaw is the writing style and format. It is structured like you're reading some type of military brief from the government, where Dave and his partner are referred to in the third person, they use various names (most of which no one reading ever uses) rather than common terms like "arm bar", and uses words for what appears to be only because they have a lot of letters. It is not well written. It bothers me because I could see someone reading it and thinking they aren't very intelligent, whereas in reality the writing is just absolutely atrocious. It's like reading an English paper from a freshman where they are going out of their way to use large words in order to sound intelligent, only to realize a few years later their instructor just wants them to present ideas clearly and rationally.
Lack of clarity and readability is the death blow for this book. Rather than present the various positions in a clear and simple manner, which could easily have been done, they chose to use military speak with various verbiage seemingly plucked from a thesaurus. I can honestly say I had an easier time reading Being and Nothingness by Sartre than I did this.
Do not buy this book. It is a complete waste of money. Unless you're just willing to plow through loads of crappy language, you'll never get through the first ten pages.
