I'm sure there is some cool way on the computer to mix up the names and pull one but I did it the old fashioned way--with little paper strips. I even had a disinterested party (trust me, she's 12--she's VERY disinterested) pick the winner. Joyce, aka Aphrodite, please contact me with your address so I can send the book along.
This was fun. Can't wait until I can do it with my own book.
