"When the Twin Towers suddenly reappear in the Badlands of South Dakota twenty years after their fall, nobody can explain their return. To the hundreds, then thousands, then tens of thousands drawn to the 'American Stonehenge'--including Parker and Zema, siblings on their way from L.A. to visit their mother in Michigan--the Towers seem to sing, even as everybody hears a different song. A rumor overtakes the throng that someone can be seen in the high windows of the southern structure"--Amazon.com.
