I need help!

HEEELP

Okay so, everyone's graduating it seems @_@ My cousin! My friend! Just so many D:

Anyway, I've already gotten something for Colton, the cousin. I need help getting something for Carrie, my very best friend!

She goes to church with me and my first young sister is also named Kerri :P

Hehe.

ANYWAY. She loves Harry Potter (we make such great friends <3) and she's graduating D:

I never thought this day would come <3 I'm both happy yet so incredibly sad she's already groooown Q_Q She always was younger :/

So.

For a graduating young lady who loves Harry Potter and the church, what type of gift should I give her? And don't say money :/ That's something you give when you either don't have a gift to give or the requester asks for it (and she didn't say, so I really wanna give her a gift!)
