Ideas for Bat Mitzvah Gift? 10 Points for Best Answer!?

I am wondering what I should get for my friend. She is turning 13, and is having a Bat Mitzvah. Her Bat Mitzvah is one week away and I have to order it, so if it could be prompt answering, that would be fan-freaking-tastic. :D Thank you so much in advance! BTW, her name is Maddie if it is needed.
