Adult Horse books
Hey everybody, I was curious if anybody has read any good horse books that are written more for adults, not adolescent girls. While I certainly loved the those books as I was growing up, I would like a more challenging read now. I don't mean "adult" wink wink, I just mean adult as in a harder read and thicker plot.
I have read Riding Lessons, Flying Changes, and Horseplay. I liked them and would like to read more like them, but something more challenging than that would be great.
Curious to read what you all come up with!
