The more you love libraries, librarians, and children's books the better you'll like this novel: Lucy the librarian is a story evangelist, spreading joy and discovery through the books she thinks are important. And without making you embarrassed about the books you haven't read, the author peppers the novel with children's books and characters that you DO know (or are almost certainly familiar enough with to understand).
I loved the way that Makkai keeps you guessing the whole book. What happens? Do they get caught? Do they go to Canada? Is she in jail? (Plus, she makes it hard to find out by sneaking a peek at the last page!)
