You can find my Good Omens fanfic Stranger in Paradise on Ao3:
Summary: Having felt left out of the Almostpocalypse, Pestilence comes out of retirement to attack London with a few plagues. Meanwhile, Crowley and Aziraphale negotiate the recent post-Armageddon’t changes to their 6000-year love affair like a couple of dumbasses and are embarrassed to discover that even Death thinks they need to get their shit together. Also Aziraphale is a BAMF.
This fic is finished and I’ll be posting a new chapter every other day!
