Every morning, the architect and writer Michael Sorkin walks downtown from his Greenwich Village apartment through Washington Square to his Tribeca office. Sorkin isn’t in a hurry, and he never ignores his surroundings. Instead, he pays careful, close attention. And in Twenty Minutes in Manhattan, he explains what he sees, what he imagines, what he knows–giving us extraordinary access to the layers of history, the feats of engineering and artistry, and the intense social drama that take place along a simple twenty-minute walk.
