Book excerpt: A brilliant, fearless journalist who knows huge areas of the Islamic world intimately, Burke now turns to the wider question of how we are to get to grips with radical Islam and what it really means. Burke has travelled all over the great arc of Islamic land, from the Middle East to Southeast Asia, and he uses this in his new book to great effect to show how various and completely unmonolithic Islam really is and how the sort of standard Western generalizations about it are both stupid and dangerous.
