Latin

You may know this from Petrona, But I am learning Latin at my knew school. i really like, we are learning about a real person living in ancient Rome, he was a banker and his name was Caecilius.
Anyway, on the search for a Latin dictionary and a learn Italian book, we found Harrius Potter et Philosiphi Lapis (Harry Potter in Latin). I had some trouble reading it, but I think it will help me a lot with Latin.
