Amazing story! Unbirth is one of my favorite genres and it's so poorly underrepresented. The pace was just right and the ending was great. I have a question though, what country are you from? I know the US is the only country that doesn't use the metric system but all the same it was a little hard to follow the centimeters at the beginning. However, as the story went on, it felt almost like a countdown and added to the story nicely. All around great job. 9/10 from me!
