For twelve long years, the grim fortress of Azkaban held an intamous prisoner named Sirius Black. Convicted of killing thirteen people with a single curse, he was said to be a loyal follower of the Dark Lord, Voldemort.

Now Black has escaped, making a seemingly impossible breakout from the Dementor ridden prison. The wizarding world is plunged into panic and while the Ministry of Magic struggles to track the convict down, there are whispers that he’s coming after Harry Potter.

Harry isn’t safe, nor even within the walls of his magical school, surrounded by his friends. And, on top of it all, there may be a traitor in their midst
