I generally prefer to read non-fiction books rather than fiction stories. So most of the fiction books I read are children's books, and a favorite is "The Little House" by Virginia Lee Burton. It's such a sweet story about a little house personified and aging, but cared for by a loving family. I love the illustrations and how it shoes the passage of time. I especially remember watching the Disney video as a kid, and when I realized it was also a book, loving it even more.
Here's the Wikipedia article, and here is the Disney video:
