Anything Can Happen - Harry Potter

Lydia Aston has always known she'd go to Hogwarts. She's normally pretty quiet and shy, and it surprises her that immediately on the train, she makes friends. But what surprises her even more is that she's placed into Slytherin. Not that that's necessarily a bad thing. Lydia becomes best friends with Harry, Ron, Hermione, and Draco in her first year at Hogwarts as her world quickly unfolds.
