In general, no.
For one, it’s about magic…which is assur.
Furthermore, the books demonstrate bad middos, inappropriate speech, the protagonists steal things from teachers, do not obey the school rules, put themselves and other kids in danger, show disrespect for teachers, there is a lot of violence, and the later books discuss very dark concepts like tearing your soul apart, and the later books contain romantic scenes.
I know what you will say…the reality is that even frum kids speak inappropriate occasionally, etc., but I still wouldn’t recommend davka giving the books to a frum kid.
Personally, I was exposed to the HP books as a child and I have fond memories of them. I would have no issue with her reading them as long as she is mature enough to decide to read them for herself.
Why not read The Hobbit and the Lord of the Rings trilogy instead? It is a lot more tasteful. And they’re classics.
