Title: Fearful Symmetry
Word Count: 41134
Author's Summary: An ancient hall of mirrors, an all-too-recent dance of death; the Doctor unexpectedly encounters an old friend, but their reunion (and Amy and Rory’s honeymoon) will have to wait. There are worse things than cracks, it would seem, in this rebooted universe…
Characters/Pairings: Eleven, Amy, Rory, Other Characters
Warnings: Explicit Violence, Swearing
Recc'ed Because: This is an edge-of-your-seat adventure story with gothic horror, special mystery guests, monsters, mirrors and well, just about everything you'd want to start off your Halloween weekend. jjpor is a very prolific writer and judging from the recs here on this site, anything you click on of his will be well worth the read. This story is no exception. Tone, pace, dialogue, plot, description... all of it comes together to tell the story of what happens when time travelers spend too much time looking in (through?) mirrors. Creepy, mysterious, terrifying, triumphant, and with a fantastic cast. Yes, anyhow, go read it!

The song swelled, distant and alien but full of love, a light in the dark, warmth in the cold, and she didn’t know whether she was dreaming any more or if it was real, not that that was always a meaningful distinction either. All she knew was that he had come back for her and…
And then she woke up, but the song was still there, right on the edge of her hearing, all around her, surrounding and cocooning her just the way the soft, warm bedclothes did.
