Lillian Angelica Potter (Year 2)
This year many suprises await for the gang of friends. There's a new Defense teacher because the last one was in league with Voldy, someone opened the chamber of secrets, people are being petrified, and on top of all that, someone, or should I say some people, have a crush on Lily.
(P.S. If you haven't read the first book in the series, you might want to. If you don't, you can probably still figure out what she's like and what happened and all that)
