Harry is in for his most dangerous year yet. Menacing monsters that literally, you can't tell from your own pet. A few troublesome, very large snakes, and deatheaters that have a few new tricks. But on top of it all, a small black book that means a load of trouble. Plus, the emergence of a school of magic that has stayed hidden for centuries. And four of its most powerful students, come to Hogwarts, with a rather deadly intent. The Malfoys are cooking up trouble, and find themselves in grave danger. And a woman from the past, keen on the entrance of a certain young wizard into a deadly school.
