Query: Harry Potter

I never thought I would become a fan of the Harry Potter series until I happened upon the movie. After seeing it, I decided to read the book and I'm glad I did. It's better than I could've imagined, making great use of suspense, foreshadowing, and symbolism. The characters are defined so you feel as though you've known them all your life. I can't wait to read the other books!
