I loved how you based it on the astrology signs - imagining something familiar in a new way. It really helped to build the world even in such a short space.
The main character, Aurelia. I love the reveal at the, though I'd like to see a bit more hints about that earlier in the story. She seems a bit docile at the beginning given what you find out at the end, so maybe show a bit more of the fire at the start.
I think you could explain what the offseasons are a bit more - is everyone from one culture expected to give birth in the same month? I'd like to see a bit more explanation on how this works and the cultural norms around it. I'd also like to see a bit more description on how the characters look, especially at the beginning. And maybe a little more on why she, as the sister, was the one who had to deliver the child?
This is really good! You build the story really well and keep the characters limited and different enough that I feel like I know them even with such a short excerpt. You build the atmosphere and world really well - it's really immersive.
I really love the action at the end, could you add a bit more into the beginning? Maybe introduce the prince a bit earlier in the story?
