Query: A good book but...

The title of this book is a little misleading. I would not call it the confession, but rather biography of Donald Cabana who worked in the prison system for a number of years and, as warden, oversaw the execution of two people.The book is very well written, easy to understand and is, in my opinion, quite humble. Donald Cabana had a remarkable and varied career. His feelings about capital punishment, especially after personally overseeing executions, are interesting to read about. There are not too many books from this unique point of view.If you're looking for detail on the death penalty process or execution technology then there are better books to read. If you are looking for an interesting biography with some insights into relationships between prison staff and inmates, then this is the perfect book.
