For Harry Potter, it’s the start of another far-from-ordinary year at Hogwarts when the Knight Bus crashes through the darkness and comes to an abrupt halt in front of him.

It turns out that Sirius Black, mass-murderer and follower of Lord Voldemort, has escaped – and they say he is coming after Harry.

In his first Divination class, Professor Trelawney sees an omen of death in Harry’s tea leaves.

And perhaps most frightening of all are the Dementors patrolling the school grounds with their soul-sucking kiss – in search of fresh victims.

Ever since Harry Potter had come home for the summer, the Dursleys had been so mean and hideous that all Harry wanted was to get back to the Hogwarts School for Witchcraft and Wizardry. But just as he’s packing his bags, Harry receives a warning from a strange impish creature who says that if Harry returns to Hogwarts, disaster will strike.

And strike it does. For in Harry’s second year at Hogwarts, fresh torments and horrors arise, including an outrageously stuck-up new professor and a spirit who haunts the girls’ bathroom. But then the real trouble begins – someone is turning Hogwarts students to stone. Could it be Draco Malfoy, a more poisonous rival than ever? Could it possible be Hagrid, whose mysterious past is finally told? Or could it be the one everyone at Hogwarts most suspects… Harry Potter himself!
