The Pure Gold Baby by Margaret Drabble

Jessica Speight, a young anthropology student in 1960s London, is at the beginning of a promising academic career when an affair with her married professor turns her into a single mother. Anna is a pure gold baby with a delightful sunny nature. But as it becomes clear that Anna will not be a normal child, the book circles questions of responsibility, potential, even age, with Margaret Drabble’s characteristic intelligence, sympathy, and wit.
