Flying Changes is one of the last really good books I have read. It is mainly about the relationship between a mother, daughter and grandmother, but it revolves around the riding school that all three women run. Even if you don't own horses (which I don't) it is easy to get swept up into this book and the drama that surrounds these women.

Sara Gruen also wrote Water For Elephants which I would highly recommend.
