There's a new rule at South School—if you misbehave, you go to the Suspension Room (or "the Dungeon," as the students of Room 2B call it). The rumors are flying about what actually goes on down there, but Harry won't be satisfied until he finds out for himself. 

題材貼近校園生活及同儕相處，容易引發學生共鳴，美國School Library Journal推薦Grade 2-3閱讀，一般國小高年級與國中適用。
