bookNow in Paperback! The story of the hard-hitting, hard-drinking Gilded Age boxer who became the country’s first sports superstar and Irish-American hero



“Christopher Klein gives readers a ringside seat for one of the greatest boxing careers in history. The descriptions of the fights are quick and powerful—like one of John L.’s punches—and the Boston Strong Boy’s life story unfolds with wonderfully vivid detail. The Sweet Science deserves beautiful writing like this.”

—Bob Halloran, author of Irish Thunder: The Hard Life and Times of Micky Ward and Impact Statement: A Family's Fight for Justice against Whitey Bulger, Stephen Flemmi, and the FBI
