Ooh speaking of 60's Crowley, can you recommend some fics with that? I feel like he doesn't get enough love compared to the other time periods
You were an Angel Once by cyankelpie
In the photo, Crowley lounged across the corner of a park bench while Aziraphale sat on the other side, his mouth open in a laugh at something that Crowley had said. All the blood drained from Aziraphale’s face. “I-I can explain.”
“Oh, there’s no need,” said Michael sweetly. “I’m sure I already understand.”
With a great effort, Aziraphale tore his eyes from the photo and looked up at her.
“Truly admirable,” she continued, “to try saving the soul of a demon.”
(Aziraphale has two years to save Crowley's soul and convert him back into an angel. If he fails, he will be ordered to kill Crowley with holy water.)
Anywhere You Want to Go by ninaloveshiddles
Aziraphale utters the heartbreaking line: "You go to fast for me, Crowley." But what if Crowley hadn't let him leave the Bentley? What if things bubbled up until there was no choice but to let everything burst?
Smut in chapter 3 ;)
You’re All I See by The_Bentley
London 1967. A holy water obsession leads to hard decisions being made, capers being planned and favors being returned, even though some angels claim certain demons go too fast for them. But Earth’s time is running short because 6000 years will be here soon. Is it better to love your Enemy from a distance or enjoy a brief relationship with him before the Apocalypse happens?
Explicit rating is for Chapters 2 and 3, and 4 is probably more on the Mature level.
