Veteran rapper LL Cool J has written an autobiography, entitled "I Make My Own Rules" (St. Martin's). In it he talks about his evolving life, from violent beginnings to his entrancement with rhyme and rap in high school, an obsession that made him Def Jam records' first recording artist at age 15. Mostly recognized throughout his recording career as the one with the gold chains and floppy hat, LL is also a two-time Grammy winner, actor, husband, father of three, and role model for youth.
