So, I was trolling around the 'net looking for more Nero Wolfe fan fiction (of which there is not nearly enough), and I stumbled into a new fandom. Uh oh. Good Omens! So far, my favorite Good Omens stories have been this Good Omens series by Macx. The series is slash, Aziraphale/Crowley, and mostly concentrates on their relationship and the changes that have resulted because of it. (The later stories begin to delve into the burgeoning relationship between Michael and Beelzebub, as well, but Aziraphale and Crowley remain my favorites.) The stories are of various sizes, and most can be read as stand-alones, if you don't have time to read them all in one go. It is best to read them in order, however.
