The Good Son by Mark Kriegel Book

Written in 2012. There is an old label on the dust cover.
This is the life story of Ray “Boom Boom” Mancini. In the early 1980s, Mancini was more than the lightweight champ. He was a national hero. Sinatra fawned over him. Warren Zevon wrote a tribute song. Sylvester Stallone produced his life story as a movie of the week. After all, an adoring public considered Boom Boom the real Rocky. Lenny Mancini—the original Boom Boom, as he was known—had been a lightweight contender himself before fragments of German mortar shell almost killed him in 1944. By winning the championship just as he vowed—for his wounded father—Ray produced his own feel-good fable for network television. But it all came apart in a brutal 1982 battle against an obscure Korean challenger. Deuk Koo Kim lost consciousness in the fourteenth round and died within days.
