Fic Recs

I've been struggling to find new (or old) fic that is engaging and inspiring.

My fandoms are:
Buffy/Angel
Firefly/Serenity
Harry Potter
Leverage
Sex Education
Stranger Things
CSI
NCIS
Stargate
Stargate Atlantis
Valdemar (book series)
Dawson's Creek
The OC

That said, I'm willing to try new fandoms too!

Any suggestions?
