Fic Title: Not With A Whimper
Author: Twisted Slinky
Link: Twisted Slinky's Fanfiction Emporium - Fic: Not With a Whimper - Supernatural - Meg/Cas
Rating/Warning(s): Mature, violence typical of zombie apocalypses
Why This Must Be Read: AU from the season 8 finale, wherein Meg and Castiel are both newly human and struggling to survive in a brave new world of fallen angels and rising zombies. The thorniness of the character's dynamic is nicely rendered, there's a lot of understated emotion, and a genuinely touching connection that transcends their desperate circumstances.
