True. I was around 9 when I got into HP and 15 when the last book came out so it hit me right at the appropriate age where the books get slightly more serious as you grow up but you're still a kid who is into the book universe. The lore or some of the overarching plot points don't make too much sense when looking at them with adult eyes but you still have to give Rowling credit for writing books that are just difficult to put down for someone at the right age.
