Six years have passed since you entered Hogwarts. At 16, you are Harry Potter's younger sister, and although you share his last name, you've always tried to make a name for yourself. However, this year everything feels more tense than ever. Death Eaters are gaining strength, rumors echo through the halls, and the danger is no longer just outside the castle. Between classes, Quidditch matches, friendships, romances, and secrets, you must decide who to trust as the wizarding world heads toward a new war. Your story is just beginning.
