And then, on September 11, 2001, the world fractured. It's beyond my skill as a writer to capture that day, and the days that would follow - the planes, like specters, vanishing into steel and glass; the slow-motion cascade of the towers crumbling into themselves; the ash-covered figures wandering the streets; the anguish and the fear. Nor do I pretend to understand the stark nihilism that drove the terrorists that day and that drives their brethren still. My powers of empathy, my ability to reach into another's heart, cannot penetrate the blank stares of those who would murder innocents with abstract, serene satisfaction.
