Short Summary Firerose Potter, Harry’s younger sister, arrives unexpectedly at Hogwarts halfway through the school year. She’s beautiful, sweet, goofy, brilliant, and secretly carries a painful past known only to her family, McGonagall, Snape, and her childhood best friend, Ginny Weasley. McGonagall adores her, while Snape secretly sees reminders of Lily in her and has privately tutored her in Potions. Ginny and Firerose have been inseparable since childhood. Her arrival catches everyone off guard—especially Draco Malfoy, Fred, and George, who each develop feelings for her. As friendships, secrets, and romance collide, Firerose’s presence changes Hogwarts in ways no one expected.
