LOS ANGELES — Oprah Winfrey has selected “The Twelve Tribes of Hattie” by first-time novelist Ayana Mathis as the second book in her newly re-branded book club, the media mogul said on Wednesday. Oprah's Book Club 2.0 will test whether Winfrey can sustain her power to propel books onto best-seller lists without her daily TV talk show, which she left in 2011 to focus on cable network OWN: Oprah Winfrey Network and her magazine O, the Oprah Magazine. — Reuters
