The stories were in an audiobook.
I believe this specifc story was in a second person pov. But not 100% sure.
Maaaaybe? Had words like "Fire, fire maiden" which might have been in the title of this specifc short story or just words used in the story itself.
The girl was some kind of warrior for some people who had made her into this killing machine where she conquers and fights whereever she is commanded. I think the first time she dies she gets killed by a boy who she had refused to kill, because he seemed so young.
She then dies and gets revived by what I think was a religious ritual that had been done in the past by these people she serves. And then she goes to fight again and does kill the boy this time and then moves onuntil she dies again by something new, and then this repeats for some times. While I think her mind gets more unstable or something.
There was also this squire friend that the girl had, who I think she devolped romantic feelings for as the loops progressed.
