This is a Harry potter fanfic in which Harry has a twin sister. When they turn 11, they find out they're wizards from Hagrid. But Harry seems to be well known while Gemini is more of a shadow in his fame. She gets sorted into Ravenclaw and grows close with a particular blonde haired Ravenclaw girl, named Luna Lovegood. What does Gemini do when she's faced between Harry and Voldemort, and the killing curse once again? Does she run back to the same Ravenclaw she found comfort with or stay to save her brother?
