Sunset Shimmer is no spring chicken, that much is for sure. Her best days are a long, long way behind her. Content to live in the human world without settling into any sordid romances, she set her scientific mind to good use, and pursued a career that left the world in a better state than it was when she first arrived. A lifetime ago. But nobody, not even an equine-turned-human, is immune to the passage of time. And as an elderly Sunset settles down to enjoy a quiet evening on the porch of her small cottage, an old friend pays one last visit.

Anon-A-Miss occured before Winter Break, and tore down everything Sunset had built up to prove she had changed. She's the main victim of this deadly online secret teller, and everyone believes she's guilty. Including her so called friends.

It takes her to a point of no return, but at last minute before she jumps, she's saved by an unlikely ally... does she even a right to that word anymore?
