Clear Light of Day by Anita DesaiRead about another book on the list.
This novel is set in old Delhi, in a crumbling family house in retreat from the louder, newer city outside. Every family has its own personal version of a national crisis and this is the Das family’s Partition story. Novels are not history books but there’s an emotional accuracy in this novel that shows how cities and countries can split over religious and cultural differences.
