Oprah Winfrey writes emotional tribute to 'Beloved' author Toni Morrison

Toni Morrison, author and Nobel laureate, has died at 88. Morrison's work captured the joys and heartbreak of black American life. "Beloved," her best known novel, published in 1987, was based on a true story of a runaway slave. It was later translated to a movie that Oprah Winfrey co-produced.
