Excellent book. Just what i needed to learn more about squash. It already make me change some misconseptions about the game technique that i had. It's really a very compreensive book, with focus on every aspects of the game. The technical issues are very well explained, and easy to follow and understand, even from someone whos first language is not english (wich is my case).
It has lot's of explanatory images and schemes about the matters explained, and very useful comment's about their real squash experience by famous player's like Jansher Khan and Ross Norman.
All in all, a must buy book.
