Mosab Hassan Yousef, son of a Hamas founder, recently authored "Son of Hamas".
In it he describes his life, from his youth during the birth of the revolutionary force in the Holy Land, through his work as a secret agent for the Mossad, and eventually his life-changing conversion to Christianity.
I came upon an article about the book.
Perhaps his most profound, and controversial, statement from the article is this:
"The problem is not in Muslims, The problem is with their God. They need to be liberated from their God. He is their biggest enemy. It has been 1,400 years they have been lied to."
