This story is a sequel to Changing Cherries
Cherry's spontaneous night changes make her, in many ponies' eyes, a changeling-like freak. But one night, an innocent dream turns into a nightmare that leaves her no place to hide. (Unfortunately, an unauthorized sequel to a story by Shaslan; I wrote this sequel for complicated reasons, but I don't promise that my reasons were necessarily any good.)
It turns out that Shaslan is working on at least one more chapter to Changing Cherries. So you could go read that story instead of this one?
I have edited this title, description, etc., and moved the original texts of those to the Author's Notes. I wrote that stuff hastily while in a bad mood. In fact, I wrote and posted this story hastily while in a bad mood. Are you sure you don't want to go read something else instead?
