Since we're on our flash forward, I'll start with some recs from one of my favourite annual communities - summer_of_giles

Giles/Cordelia is not a pairing that I automatically think about, but I’m always surprised how well it can work if done well and in aadler’s Better Left Unspoken, it is done very, very well. These are snapshots of Giles and Cordelia through the Sunnydale High years and beyond in a way that makes me both laugh out loud, and made my heart hurt. This is good stuff.
