Thank you. I agree--I love exploring, especially the library.
I'm Muggle-born, and one of the things about magic that still surprises me is time travel. I've always wondered what it would be like to meet my parents when they were my age--or to meet a future child. It's not as much fun as I thought it'd be.
Madam Pince probably knows a good book. I did some...searching in the library today while waiting for a friend, and there seems to be a wide variety available.
You mentioned you're a sixth year. Just curious...what courses do you take?
