I have great respect for the author's pursuit to heal through music, but this book was a huge disappointment for me. There is no substance. We never get to know any of the inmates. We don't know whether any of them were helped or healed in any way, or whether the music classes were nothing more than a fun escape from prison drudgery. Martin tells us over and over that he works with at-risk kids and can't wait to take everything he learns at and about the prison back to them. Yet, we don't go there with him. We don't see how the kids react to his stories, or whether any of them learn a single thing.
The book reads like a journal, with each entry taking us on his trip to and from the prison. We go through the gates and walk the grounds over and over. The first time was interesting. After that, it was needless repetition. At one point Martin gets trapped in a prison lockdown, but I never felt the urgency. In the next paragraph, it's over and he's heading home.
Several times, Martin refers to the inmates as wild dogs. He doesn't seem to have the slightest respect for any of them. He may indeed have much respect, though what came across in the writing was a condescending and fearful attitude. The ending is abrupt and, I thought, came on a sour note. Martin was startled and horrified that an inmate had found out where he lived. Well, he used his real name. They're inmates, not idiots. What did he expect?
Again, I respect the author's goal. This book, though, would have greatly benefited from the input of a good editor.
