The publishing world has been dealt a major blow courtesy of its biggest booster: Talk show queen Oprah Winfrey has decided to end her phenomenally popular monthly Book Club. "It has become harder and harder to find books on a monthly basis that I feel absolutely compelled to share," Winfrey says. "I will continue featuring books on the Oprah Winfrey Show when I feel they merit my heartfelt recommendation." Toni Morrison's novel, Sula, will be featured as the club's last selection.
