What does the lobby of the North Tower look like in the novel, Ground Zero?

The lobby of the North Tower is as wide as four tractor-trailers parked end to end. It is so tall that you could stack tractor-trailers three high and still not hit the ceiling. Up above is a wraparound mezzanine where a second floor would have been. Sunlight bounces off the windows of smaller buildings across the street and makes the North Tower's lobby glow.
