In the introduction to her stunning first novel, Padma Viswanathan describes her grandmother’s faltering attempts to recount their family history. “This time, she started farther back,” she writes of one occasion, “with a story I’d never heard: of her own grandmother, married as a child and widowed before she was out of her teens; of that grandmother’s son, childless and embittered; and her daughter, my grandmother’s mother, victimized by her marriage.” After trips to India, enormous amounts of research, and not a little invention, the result is The Toss of a Lemon.
