Do you have multiple copies of any of your books?
If so, why? Absent-mindedness? You love them that much? First Editions for the shelf, but paperbacks to read?
If not, why not? Not enough space? Not enough money? Too sensible to do something so foolish?

I have OFTEN bought multiple copies simply because I will be intrigued by the story again and not realize that I have read the book until I am 20-30 pages into. Historical romance authors get me like this all the dang on time because they change covers.....

Deathly Hallows......DONE

Its done.....I have finished it with a heavy heart....saying goodbye to the Hoogwarts Crew was very hard. It was even harder to see some of my personal fave characters (no spoilers) die. This is definitely a much different book than the first one but I love the progression. Ms Rowlings did a wonderful job with the entire series....wish I could say the same for that crappy movie....It SUCKED.....We saw Ratatouille and HP: Order of Phoenix and the first was a good. Nothing I would watch over again but HP was TERRIBLE. All sliced and diced almost beyond recognition.
