Madeline Lupin finally gets to return to Hogwarts after Umbridge's impromptu leaving, something the now twelve year old is forever grateful for. But what Maddy fails to realise is that this school year may be even more chaotic than the last; which is to say, a lot. New teachers, new clubs, a new Quidditch captain, and Darienne Lomen joining in Maddy's tutoring sessions, Maddy must learn that to survive at Hogwarts in the middle of a war, you need to make sacrifices. And let certain promises wither away. Maybe the Sorting Hat was right last year.
