My daughter and I just finished reading the entire Harry Potter series together. It took us a whole year. Every night we would take turns reading. What a journey it's been, both in terms of the story, and for us. It was like for a year we shared our own special magical world with our own language and our own inside jokes.
So now that we've finished the books, we decided to watch the movies together as a family. (My husband had read the whole series earlier.) It's given us a new way to enjoy Harry Potter, and there's so much for us to talk about and debate as we compare books to movies.
