If there’s anything a bookworm loves more than books, it’s books on books. After all, we love talking about books and reading books, so why wouldn’t we want to read about books, too? I’m charmed by books like The Cat Who Saved Books and Mr. Penumbra’s 24-Hour Bookstore set in bookshops. And few books have hit closer to my heart than The Sentence, set in a fictionalized version of author Louise Erdrich’s bookstore, or The Book Thief, about a girl who saves books from being burned in Nazi Germany. It probably has something to do with the fact that few things are closer than a bibliophiles heart than books, so stories that look into the sacred space that books hold in our hearts will of course hit a little harder. And those books focused on the subject of books, libraries, and bookstores aren’t confined to the world of fantasy, romance, or contemporary fiction, either. There are plenty of historical fiction books that explore the importance of words and literature, too. These four are just a few of my favorite.
