Mostly I read nonfiction, for two reasons: it's essential for the work I do. And I like reading about the real world. But once in a while I wander. This summer I've dined on a smorgasbord of books. Most recently a terrific novel by Anthony Doerr, "The Light You Cannot See." It's a World War II tale and, no question, novels at their best heighten and help explain the real world. This does both. For those of you teaching WWII, I especially recommend it.
