Author Lawrence Wright was a conscientious objector during the Vietnam War, which meant he was required to do two years of what was called "alternative service." He ended up in Egypt, teaching at the American University in Cairo. And it was there that the man from Texas started his obsession with the Middle East.
Since then, Wright has written a lot about the region and about terrorism as a staff writer for The New Yorker. Now, he has compiled his many New Yorker essays into a new book called The Terror Years: From al-Qaeda to the Islamic State.
