Nobel Prize winner Toni Morrison is America's first lady of literature. Her books encompass black American history but live and breathe in the present, rich in vivid characters, haunted by ghosts. Born poor in Ohio in 1931, she now lives in New York. She tells Alan Yentob how her father hated whites so much he wouldn't let them in the house. Her masterpiece, Beloved, shows the horrors of slavery perhaps better than any other artwork. She talks as she writes - with warmth and wit. Contributors include Angela Davis (whose biography she edited) and singer Jessye Norman.

His gigantic balloon dogs and even bigger flower puppies have become iconic. His rows of virgin vacuum cleaners are frozen in time. Michael Jackson sits with his pet chimp Bubbles.  But the artist who celebrates the commonplace and has put sex and the banal on a pedestal has mined some dark territory. Is it playtime or parental guidance recommended? As Jeff Koons' first retrospective takes over the Whitney Museum in New York and the Pompidou in Paris, imagine... asks what lies beneath the shiny surfaces.

Jeff Koons: Diary of a Seducer

On the brink of the Depression in 1929, Georgia O'Keeffe - America's first great modernist painter - headed west. In the bright light of the New Mexico desert, she forged an independent life and found the solitude she needed for her truly original art. The photographs taken of her by her older lover scandalized the public. Her flower forms were seen as a shocking and vibrant display of femininity, her bones and skulls as surreal and disturbing. Now, 30 years after her death, to coincide with a major Tate Modern show, imagine - tells the story of Georgia O'Keeffe, one of the most inspiring artists ever.
