Northanger Abbey
The fluffiest Jane Austen book, but it's so short that it doesn't matter.
I enjoy Catherine as a heroine, even if she's extra naive at the beginning, but I'm a sucker for stories about people who can't separate real life from fiction. Only four stars, though, because Austen spent too much time in Bath and not enough time with Catherine believing Northanger Abbey is haunted by secrets. (I'm also a sucker for old houses, especially if they have secret passages and hidden rooms.)
