I'm looking for a fanfiction that's about Harry Potter's sister, it turns out that they didn't grow up together. Harry grew up with his uncles but Lyra grew up as Viktor Krum's adoptive sister. When the Triwizard Tournament arrives, they meet and George falls in love with her. George calls her "pretty Lyra" and she has a kind of "power" that he inherited from Lily, this comes out in a scene where they are in the hallway and Severus scolds her for something (that I don't remember) he was so angry that instead of seeing her She saw James Potter and ended up taking her by the arm and pulling her until she fell to the ground. Severus continues pulling her to take her to the headmaster's office because of her bad behavior and she doesn't realize that Lyra's hair is started to shine.
