It may be impossible for an author to achieve more acclaim than Toni Morrison, now 81, who won the Nobel Prize in literature in 1993. Her work is “characterized by visionary force and poetic import,” the Nobel Committee wrote, and we’ll get more of it May 8, when her 10th novel is published. “Home” is the story of an angry African-American veteran of the Korean War who returns unhappily to the Georgia community where he was raised.
