Addy Potter has missed her first three years of Hogwarts. As a brand new fourth year, she already knows her experience will be nothing like the average Hogwarts student's. With living up to her older brother James's insufferable legacy, catching up on years of missed studies, and brewing war, she has to adjust to this new life quickly. And a certain Slytherin boy and his Gryffindor brother do not help the matter.
