Harry Potter.
I just bought the latest HP book. I went to pick up some dummy cakes, and Barnes & Noble is across the street. My 12 yr old son says "can we go to barnes and noble? there's this book I want to see if they have". Mind you, he has the whole HP collection. Needless to say, I bought the book.
He finished it the same day!
Last week, my husband and I went into the Village, and there was a HP festival- complete with long lines and tons of kids wanting to see "Harry Potter". The book went on sale, and lots of bars and clubs in the area were having "HP parties". Hilarious!
