Has anybody read this book about bjj?

"Mastering the 21 Immutable Principles of Brazilian Jiu Jitsu" by Paolo Guillobel? I can only see the table of contents but it sounds good. Anybody read it or know about it?

Let us know what you think. Glad you were willing to take the chance. I want to hear somebody's opinion before I buy it.

For Kindle? How much? Phone Post 3.0
