I too get a lot out of books I read more than once, and there are many favorites that I have read multiple times. I tend to read too fast and miss a lot the first time, or times. And there are others where I enjoy being with the characters so much that I want to re-visit them many times again.
When my children were first born I was looking forward to sharing my favorite childhood works of fiction with them. But they are not big fans of reading fiction (they prefer reading non-fiction). But now we're listening to books on CD while driving, and we all are enjoying them. The boys like listening to the stories as we drive along, and I'm discovering a wonderful new dimension to old favorite books by listening to them read aloud.
Right now we're listening to the Little House on the Prairie books. That's a series I've read many times over. I especially like to read The Long Winter right before a hurricane hits my town. I figure if the Ingalls could bravely survive 6 months of blizzards then my family can certainly face whatever one hurricane can do to us.
