If there are any ARC readers here, if it doesn't give anything away, do you know what the 3rd book in the series is going to be called? I've been wondering.
If it takes a while, the actors will probably get too old ... and making the 3 books into movies as well. I was going to say that HP was okay, and the movies took a while to make and come out, but then I realised that the characters are meant to grow up, so it's okay.
