[Book 3 of the Cassiopeia series] It's the seventh and last year at Hogwarts of Cassiopeia Moore, and the wizarding world seems crazier than ever. Sirius Black is still a killer on the loose, Harry Potter and Dumbledore both appear as lunatics for the Ministry, dark wizards are lurking around, and, to top it all, there is a new teacher at school that will not make things easier for anyone. How will Cassie survive all that when she also has to study for the approaching NEWTs? Well, with her friends and family, of course. And, specially, with George Weasley.
