The Shadow Lines by Amitav Ghosh is a personal favorite. I re-read this thinking that my love for it was misplaced but, surprise, it was not! One reason is Tridib, the central character, who functions as Ghosh’s mouthpiece.
Themes: home, memory, relationships (between generations), history, and borders (geography).
Place: “I could not persuade her that a place does not merely exist, that is has to be invented in one’s imagination… so that although she [Ila] had lived in many places, she had never traveled at all” (21).
