It was 2 a.m. when I found her name.
I’d been falling down a research rabbit hole for hours—cold coffee, candle burning low, browser tabs multiplying like they do when you’re chasing something you can’t quite name yet. And then there she was: Nadezhda Popova. Soviet pilot. Night Witch. 852 combat missions flown in a plywood biplane with no radar, no parachute, and no business surviving any of it.
She was 19 years old when she started.
I sat back from my screen and just… sat with that for a while. Because here was a woman who had changed the course of a war — who had terrified the German army so badly they gave her regiment a name they meant as a slur, Nachthexen, Night Witches, and watched it become a badge of honor instead — and I had never heard of her. Not in school. Not in any of the war films I’d grown up watching. Not anywhere.
It’s a pattern of upholding the contributions of men while taking advantage of the bravery and sacrifice of women.

Women have been present at every turning point in history. In every war, every revolution, every moment where the world cracked open and reformed itself into something new — women were there. Strategizing. Sacrificing. Bleeding. Winning. And then, with breathtaking consistency, being written out of the story before anyone thought to write it down.
I’m Astrid Cartesian. I write historical fiction because I am done with that pattern.
My debut novel, Operation Nachthexen, follows Senior Lieutenant Nadezhda Kozlova — a Night Witch pilot shot down behind enemy lines, cut off from her unit, fighting through occupied territory toward a mission that could shorten the war. She is fierce and frightened and brilliant and running on empty. She is built from the real testimony of women who actually flew those missions, who actually survived those conditions, who actually did things that should be impossible and did them anyway.
This is not a war story with a woman in it. This is a war story about what women carry — and what they refuse to put down.
Here, we don’t do sanitized history that only recognizes men. We don’t do footnotes that apologize for the brutality. We go all the way in, because the women we’re writing about went all the way in first, and they deserve nothing less than the full truth of what they did.
If you’ve ever finished a history book and thought — but where are the women? — you just found your people. This is where we fix that, one story at a time.
