I loved the movie Wild Hearts Can't Be Broken. When I learned the movie was based on the true accounts of Sonora Carver I had to read it. It seems the only thing the movie had right was she rode diving horses, she went blind, and she continued after. If you loved the movie I would recommend reading the book. I loved the details you learn about the horses as well.
While the writing was good I found the story slow. Also, the paranormal parts were hinted at and most of the book was quick to rap up in the last 50 pages or so and felt rushed. I think this just suffered from first novel but I don't think I'll continue on with this series anytime soon. I would consider reading a different series by the same author though.
