Good Piano Song for Final Concert?

I'm coming up on my second and final year of piano in high school and
I'm looking to purchase sheet music for the two concerts we have. For
the end of the year one, I'm trying to find a piece with a title that
suits, i.e. anything to do with leaving or remembering. Or even just
an incredibly beautiful piece. Something outside the box of A River
Flows in You and the usual. Suggest anything; even though I'm only
going on my second year, I played Grace by William Joseph at this past
end-of-the-year concert and am looking to increase my skill set. Thank
you!
