A few years back, I read Josh Hamilton: Beyond Belief and I would definitely recommend it! I knew Josh's back story from various articles that I had read, but this book goes into a lot of detail and is 100% from his perspective. Throughout the entire book, it sounds as if Hamilton is sitting across the room from you narrating the entire thing.
Even if you aren't a baseball fan, I would recommend reading this book. It is an amazing story and you get a closer look into the daily battle and the stories of a recovering drug addict and alcoholic. It shows how each day truly is a struggle for Josh and everyone else who is battling a similar fight against addiction.
