Colum McCann's novel "This Side of Brightness" tells the story, of amongst other people, the men who dug the railway tunnels under New York, and the homeless people who now live in those same tunnels. McCann, who is in the Twin Cities to read from his book tonight, was born in Dublin, but has lived in New York for some time. He told Minnesota Public Radio's Euan Kerr he was attracted to the story of the tunnel-diggers because they broke ground with more than just their shovels. Author Colum McCann will read from his novel "This Side of Brightness" at the Hungry Mind in ST Paul this evening at 8. Sun 28-MAY 11:36:39 MPR NewsPro Archive - Wed 04/11/2001
