The Philosopher's Stone

Everyone knows Harry Potter, the boy who lived, defeated Voldemort as a baby, blah blah blah. Not many people know about his twin sister, Vanessa Potter. She was there of course, in the crib, but Voldemort didn't care much for her. So she's just there, not really well known, but not completely forgotten either. Now her and Harry are starting their adventure of Hogwarts. Making close friends, unwanted enemies, and many memories. Vanessa is going to try to make her mark in the world where her brother takes the spotlight.
