Nobel Prize-wining author Toni Morrison is perhaps best known for Beloved, her 1988 masterpiece that nakedly plumbed the terrible psychic and emotional fallout of slavery. Her newest novel, A Mercy, can be thought of as a prelude to Beloved, set in the wilds of 17th-century America. Touching on similar themes of lost innocence and the price paid for enduring the bonds of love, A Mercy finds the septuagenarian author still at the height of her lyrical powers. Tonight, Morrison reads from A Mercy and speaks with KQED host Michael Krasny about her remarkable career and work.
