American ground, unbuilding the World Trade Center

At the center of the book is the team of engineers, many of them instrumental in building the towers, who now must collaborate in the sad task of disassembling them. Their responses are as dramatic and unpredictable as the shifting pile of rubble and the surrounding "slurry wall" that constantly threatens to collapse, potentially flooding a large part of underground Manhattan. They are also emotional and territorial, as firemen, police, widows, and officials attempt to claim the tragedy-and the difficult work of extracting the rubble and the thousands of dead buried there-as their own.
