A Genuinely Good Guy & A Genuinely Fun Read
Format: Hardcover
A prison diary with optimism, realism and humor. You can read this book in its daily snippets, but you won't want to put it down as the daily drama unfolds. Each story leads up to the next in a riveting account of gritty survival.
Peter is a man I genuinely would like to meet some day. Every once in awhile we get blessed with a public servant who has a heart of gold. Someone who doesn't just look after their own selfish interests, but cares about the affairs of others. Peter proves to be that man.
Injected into a jail system with malice as a political prisoner, we find Peter busy helping others. When life gave him lemons, Peter chose to make lemonade for others. He discovered everything that seemed hopelessly mucked up in the prison system. So Peter, the ever-observant statistician, dug deep into the root causes of the massive dysfunction. He then began detangling each individual man's predicament with precision. And love. He genuinely cared about the prisoners and their families, their lives and their future. And when he left, he continued to work to change things for the better. That is honorable and commendable.

Well written
Format: Kindle
Navarro writes "postcard" style short chapters. Easy to read with a dash of humor in each. His prose flows well. I was captured by his efforts to improve his situation along with fellow inmates. Quite enjoyable.

It's more about a good man than politics, an enjoyable and important read!
Format: Hardcover
What an enjoyable book. It's not about Trump, it's about people, family and above all hope for the future.
Being in manufacturing, I loved his approach to trying to bring it back to America. His funny yet no nonsense approach and outlook is refreshing. He doesn't mince words.
I will forever respect the courage it took to do what he did, standing his ground, but the book is so much more!
Excellent read!
