I've recently read the Mitford series by Jan Karon. In Jan Karon's Mitford Cookbook and Kitchen Reader, there is a story she wrote for Victoria magazine, called The Right Ingredients. The following is a passage from that story.
When she was little, her father had said, "You read too many books. If I catch you reading another book, I'll throw it in the fire. Reading will rot your brain, go help your mother."
She had read in bed for years, under the covers with a flashlight, which was how she'd read every word of her second favorite book, Jane Eyre. She had nearly put her eyes out and ended up wearing glasses, which to this day she blamed on small print in paperbacks.
It doesn't say what the character's favorite book is, but I'm curious!
