How Many?

I wonder how many of us were celebrating today. Celebrating birthdays, anniversaries, weddings, the A on your test? And how many of us today were celebrating the release date of Mark of Athena? I know I was. The ending of the last book was horrible. I can't wait until it falls into my hands. The only thing that worries me is this: Why, on the cover of the book, are Jason and Percy battling each other? This does not bode well. Good luck to all of you who are now rushing to your local library or bookstore to see if it is in stock! Happy reading!
