I know this is a difficult question and many of you will say, “I can’t pick just one book!!!!” And so I will give you some parameters: You have a very good friend who is about to go on a relaxing and fun summer vacation (remember summer vacations?!?!) at a low-key and beautiful location, where she plans to lounge around by a body of water.  She needs something diverting to read while she is there. It should be fiction, from the last one hundred-ish years. It does not need to be what is traditionally deemed a “beach read” — you can definitely recommend something literary and serious, if you want! What do you tell her to pick up at her local bookstore?
