This book is simply various letters. Nelson writes his dad while his father is incarcerated. The reader sees the months passing by and hear’s Nelson‘s questions on why are things taking so long? Are you happy, when will you be home, etc. At the end of the book the author gives advice for writing letters as well as reasons and things too, and do not say. Well, I like this book and I think it does a good job, changes in our prisons and jail systems in the US may make this book useless sooner than later. For example, there are mail services that take a prisoner‘s letter, scan them, and send them digitally to the prisoner, instead of allowing them to have the actual letter. But if the prisoner can’t afford a prison tablet or device and must wait their turn on the shared device it may delay. their getting these messages for days if not weeks. And the ability to return messages also is very much impacted on the prisoners’ ability to pay. I do find it interesting that the author did not include any letters home and does not bother to explain why Dad never writes back.
