I guess this means your favorite fictional book but I dunno. The other posts say, "You favorite..." so who knows. But since I am knee deep in childrens books, its not an issue for me to pick a favorite. I'm going to have to go with a classis, "Goodnight Moon." We have over 100 books and that is probably the only one that I will read at any given moment - without a big sigh. I know reading is important but Tylee never, ever, ever tires of reading books. It gets old. I'm sorry.
