Mixed martial Arts by BJ Penn.

This book is jam-packed with hundreds, if not thousands, of pictures of BJ Penn demonstrating the techniques that made him a multiple UFC champion. The techniques are simple, effective and cover stand up, clinch and ground ranges. As you would expect from the first non-Brazilian Mundial World BJJ Champion, there is a bias towards ground techniques, but this is where the demand is nowadays. All together it is a great read, and a better reference material. Four out of five stars.
