Author Douglas Stewart writes vividly about addiction, love and queer adolescence in working-class Glasgow. He wrote Booker Prize-winning "Shuggie Bain" and the new novel "Young Mungo." And, Michael Madigan was the speaker of the Illinois House of Representatives for 36 years, the longest reign of any legislative leader in the country. A new book tells the story of his rise from Chicago machine politics and his fall from grace amid a corruption investigation.
