I didn't end up creating something this year as I'd hoped, so have a rec list instead! Some multi-fandom female-centric fics that have brought me joy. (But it's me, so most of these are Buffy, Star Wars, and crossovers/Fusions.) Full disclosure: some of these were written for me, so I'm a bit biased. Crossposted to the DW comm.
