Has anyone read the books Three Lives of a Warrior or 7 Years in Hanoi?

These are 2 books I have come across over the years. The 1st book Three Lives of Warrior is by a great local man here in the Monterey Peninsula named Phill Butler. The book is about before during and after his time as a POW in Hanoi. The 2nd book is named 7Years in Hanoi by Larry Chesley detailing his grueling experience in what was called the Hanoi Hilton.
