I am blown away that it's been 10 years since the first book in the Harry Potter series came out. It took me awhile to jump on that bandwagon but I'm so glad I did. I absolutely loved the books and have been impressed with the way the movies have followed them so closely. 
Head over to MomDot and enter their anniversary contest from Scholastic. The books are being re-released as a boxed collectors set with new artwork. Good luck!
