I don't know if I have an actual favorite book.. I do have several series that I like..
1. The Cat Who series is always enjoyable for me.
2. Anne Rice's Vampire chronicles.
3. The Doll in the Garden is a really good book..
4. Tiger Eyes, by Judy Blume was a favorite when I was younger.
So that is about it for books.. I don't have a lot in the way of favorites.. but those are the ones that I enjoy.
