Book excerpt: Steinberg takes readers through Chicago's vanishing industrial past and explores the city from the quaint skybridge between the towers of the Wrigley Building, to the depths of the vast Deep Tunnel system below the streets. He deftly explains the city's complex web of political favoritism and carefully profiles the characters he meets along the way. Steinberg never loses the curiosity and close observation of an outsider, while thoughtfully considering how this perspective has shaped the city, and what it really means to belong.
