   Summary

   Acheron wakes up every morning with no memories. And every time she wakes up there’s someone at her side, easing her fears with a warm presence. No one said love is easy… And it all started with a fateful dance.

   Aka Acheron is an eldritch horror and Black Swan isn’t much better. A little tearful and a little nostalgic. How important are memories?
