“What you fear most in the world is… fear.”

REMUS LUPIN

For twelve whole years, the dreaded prison of Azkaban housed a notorious inmate, Sirius Black, who had been convicted of murdering thirteen people with a single curse. Rumors circulated that he was a devoted follower of the Dark Lord, Voldemort. Now he has escaped, and the guards of Azkaban remember that he often murmured in his sleep: “He’s at Hogwarts… he’s at Hogwarts.” Is Black hunting Harry?

Harry Potter is not safe, even within the walls of his magical school, surrounded by his friends. And, even worse, a traitor may be among them.
