The A in Angel

"The last 24 hours had been hard for the demon to forget. He had never experienced a breakup, that was such a human thing. He had always believed that he could deal with it...well, at this point, Crowley had been wrong. Utterly, utterly wrong. So, the demon found only one way to drown away all his sorrows - which finally had ended up in excessive amounts of alcohol."

Aziraphale goes missing.
Captured by none other than - guess who - Archangel Gabriel himself, Heaven wants to take their final revenge on Crowleys angel friend. As the demon arrives at the bookshop only to find it scattered in ruins, it's up to him rescuing his angel. Whatever it takes.

Or Crowley will lose more than just the love of his eternal life...
