‘The Breath of War’ by Aliette de Bodard

I read this in Beneath Ceaseless Skies. Making a baby requires carving a third participant from magical stone who will later breathe life into the child during birth, but our protagonist carved a spaceship instead. She travels into the mountains, braving rebel activity (the rebels that killed her family, actually) in order to find the ship, because she's pregnant. The ship has been killing rebels. She wants it to go to the stars where it belongs. As usual, Alliette’s writing really shines when it comes to birth and starships. This one really grabbed me. 298/304 quanta.
