Rita Marley’s new book about her life married to and collaborating with reggae musician Bob Marley is the poster book for the great old cliché “behind every successful man is a woman.” Of course, in Ms. Marley’s case, she is not just the woman behind his success but also the woman willing to have and raise his children, promote his career, and look the other way when Bob was blatantly engaging in extra-marital affairs.
