This clearly-written text on dressage covers what is required of riders and horses, the dressage test and how to prepare for it, and how to succeed in this demanding discipline.
This book was readable - since I have a hard time reading non-fiction, that is a compliment. I took away a few tips that I hope will help in my future competitions. I didn't feel like I learned much new, but it did reiterate ideas I have heard elsewhere.
