It is a succession of several books written by J.K. Rowling. Actions in books have place in Hogwart School where three students: Harry, Hermiona and Ron have adventures. They study magic and fight in order to maintain justice, law and peace. Three young wizards are growing up and in each book conflicting with amiss sides. Books are really interesting, even not for s-f readers. I think, I can surely recommend that stream for all people.
