How about joining us for an adventure in sunny Rio de Janeiro, Brazil? We're going to discover Brazil through the eyes of Raul, Alexandre, Miguel, and Estrela Ferreira. They have a unique friendship with jiu-jitsu Grandmaster Brioso Silva, who trained them from an early age. They learned all about self-defense and about life itself. Grandmaster Brioso Silva always said, "There's a devil inside of me ... who likes to make mischief ‒ to do bad things." But he gets that devil under control and teaches jiu-jitsu along with how to be kind to yourself and others. In this book, you will be introduced to guard dogs, thieves, a monster, bullies, a warlord, flying cigarettes, and ... much, much more! Of course, I can't go giving everything away, you understand that ... I promise you're going to have a whirlwind adventure. Do you dare to take the leap? Well, in that case, what are you waiting for?
