영화와 게임으로도 엄청난 인기를 모으고 있는 해리포터 시리즈의 미국판 2편. 호그와트 마법학교에서 첫해를 보내고 더즐리 이모댁으로 돌아온 해리는 여름방학이 끝나는 날만을 기다린다. 개학을 준비하고 있는 해리에게 어느 날 집요정 도비가 나타나 학교로 돌아가지 말 것을 경고하는데...과연 해리 앞에 나타난 위험은 무엇일까?
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 possibly be Hagrid, whose mysterious past is finally told? Or could it be the one everyone at Hogwarts most suspects...Harry Potter himself!
