Everyone knows that Harry Potter is the best book related with witches and wizard, i want to try an write a book near that level ... I would 愛 to write a book with someone else who lives in the UK ...

I have no idea??????

Be careful, it must not look like a HP copy!
If you´re a great HP fan, maybe あなた can try to write a fanfiction (?) That´s possibly easier than creating a whole new world not too similar to Harry Potter!
