(BASED OFF OF THE EVENTS OF PRISONER OF AZKABAN) "The way, he cackled while he was hitting, slapping, punching, kicking me, it was like he was getting pleasure from it." Harry and Christella Potter are dreading Aunt Marge's visit in the next coming days. After she insults Harry and Christella's parents, Christella 'accidentally' blows Aunt Marge up. Before poor Christella has to cop it, again, she and Harry pack their bags to run away. They soon learn that escaped prisoner, mass murderer, Sirius Black is on the loose, looking for Harry and Christella. After many new discoveries, and one rather disturbing one, who is really innocent?
