The Immortals Quartet was my favorite as well. =) It was much easier for me to connect with the uncertain, emotionally damaged Daine than with brave, tomboyish Alanna.

Oooh, I LOVED From the Mixed Up Files of Mrs. Basil E. Frankweiler by E. L. Konigsburg! I spent my childhood being dragged from one museum to the next, and it was always fun to imagine being able to spend the night in one. I would love to spend the night at the Art Institute, although I'm pretty sure the Hall full of Armor would be inordinately terrifying at night.
