Let me tell you that so many people I know loved The Library Book by Susan Orlean. It’s probably because I work in a library and know so many librarians. I enjoyed learning about the history of the Los Angeles Public Library, I enjoyed reading about the fire that happened at the main branch in 1986 (the same day as Chernobyl, so while it should have made the evening news, it didn’t), and Orlean tells her intertwining stories well.
If you are a book person, read The Library Book.
