Caryl Phillips, author of five novels, a work of nonfiction and many scripts for film, theater, radio and television. His new novel,"Crossing the River" (Knopf), tells stories of slavery and the relationships forged by and among some of its perpetrators and victims. Phillips takes liberties with time in following the lives of three African children sold into slavery by their desperate father -- one freed and sent back to Africa as a missionary, one searching for her lost husband and child in the American wild west and one, a World War II GI stationed in Yorkshire, England.
