When Elodie Carrow transfers to Hogwarts, she quickly becomes inseparable from Y/N Black. At first, everyone is happy that Y/N has made a new friend. Then things begin to change. Arguments become misunderstandings. Friendships begin to fracture. Trust starts to disappear. While Y/N grows closer to Elodie, the people who love her most can only watch as she slowly drifts away from them. Everyone can see something is wrong. Everyone except Y/N. As loyalties are tested and relationships pushed to their limits, one question remains: How far will someone go to become the most important person in another person’s life?
