May I just say how delighted I am that someone else likes McGonagall/Amelia Bones?
They work so well as a pair, I think! I received an MM/AB story as my gift in the recent femmefest, and it's one of the best McG stories I've read recently. I'm going to give the pairing a try myself. (I've already worked a brief mention into one fic, but I'd like to try a full-fledged story.)
