Too much of a good thing?

I have found the fatal flaw in my library game: sometimes books become available before I'm finished with the ones I already have! I've just barely started "Life of Pi", and now I'm adding "Stardust" by Neil Gaiman to the top of my "to read" list, and pushing the new books I bought further down.

Now, I'm not complaining! It's nice to have so many books to read. But I don't want to feel like I have to rush through a book because I have to get to the next one, either. I hate the feeling of fewer and fewer pages between me and the end of a book I'm really enjoying. I guess I'll just have to console myself with the fact that I have several more endings to get to when I'm finished with this one!
