This was recommended to me by another teacher.
The author is a lawyer from the south who, starting in the 80s, began trying to find justice for death row inmates who were wrongfully convicted. These were people who were convicted because of race, poverty, or mental illness. They weren't given fair trials, or the evidence was so glaringly obvious that the person didn't do it, that it was clearly bigotry that convicted these people. This book made me want to yell, to cry, and to be so happy that a person like this is in the world, helping people that cannot help themselves.
I'm an avid reader. One thing I've learned in my many years on this Earth is that no matter what is happening in your life, you can always benefit from temporarily escaping life in order to become absorbed in a make believe story.
