"This is fan fiction for the Whateley Academy series. It may or may not match the timeline, characters, and continuity, but it's fan fiction so I hope it's forgivable."
Rona is from the novella "Never", and Ruth is from the novella "How Far", both of them have been in very bad situations previous to this story, and it will really help to read both of them before reading this one. Don't worry, this story isn't as quite as dark as their origin stories.
Oh yes, Mercy is dorothycolleen's character from the Whateley Fanfic Mercy. I liked the character's intro, so I asked permission to use her as a bit character, and was graciously given permission.
