Gotta reccomend The Horse Boy by Rupert Isaacson. AMAZING.

The Tao of Equus. Another great read.
The Faraway Horse - Buck Brannaman
Riding Between The Worlds - Linda Kohanov
Way of the Horse - Linda Kohanov
Movies I don't really do because, like Jessabel, I get easily irritated by them because they misrepresent horribly.
