Mosab Hassan Yousef, son of Hamas, tells of his conversion.

Son of Hamas: A Gripping Account of Terror, Betrayal, Political Intrigue, and Unthinkable Choices - newly released from Ignatius Press:

The shocking true story of a Hamas insider who rejected his violent destiny - and is now risking everything to expose closely guarded secrets and show the world a way to peace.
Since he was a small boy, Mosab Hassan Yousef has had an inside view of the deadly terrorist group Hamas. The oldest son of Sheikh Hassan Yousef, a founding member of Hamas and its most popular leader, young Mosab assisted his father for years in his political activities while being groomed to assume his legacy, politics, status . . . and power.
But everything changed when Mosab turned away from terror and violence, and embraced instead the teachings of another famous Middle East leader. In Son of Hamas, Mosab Yousef--now called "Joseph"--reveals new information about the world's most dangerous terrorist organization and unveils the truth about his own role, his agonizing separation from family and homeland, the dangerous decision to make his newfound faith public, and his belief that the Christian mandate to "love your enemies" is the only way to peace in the Middle East.
