Are there any interesting books/websites of reformed terrorists

I am reading the website of Walid Shoebat and it is interesting to get a perspective of someone who was a radical terrorist. However he became a bit extreme in the pro-Israel direction after his conversion, he is somewhat like David Horowitz in regards to him going from one extreme to another.

Are there any other books about the mentality and acts of terrorists by those who used to do these things and then reformed?

What about other criminals like military officials in dictatorships (for example, a Cambodian in the Khmer Rogue who repented), child molesters or serious criminals who reformed and tried to tell their biography, what they did and stood for and their reformation?
