Chapter 1

The helicopter blades were still chopping when my boots hit the tarmac, and I already knew what kind of morning it was going to be.
I could tell by the way they looked at me. Not all of them — some were professionals who had learned to wait before forming an opinion. But enough. The specific kind of look that moves from face to face like a signal fire when something arrives that doesn't match the expected silhouette. I was nineteen years old, five feet four, and carrying a rifle case that had seen more of the world than most of the men currently inspecting it from across the pad. I was used to the look. My father had told me I would be, on one of the last mornings we ever spent together at the kitchen table in western Montana, before his third deployment, before the flag.
He said: they will look at you before they see you. Give them something to see.

My name is Ava Mitchell. I had been shooting since I was seven. Long range since I was twelve, the year my father took me out to the far end of his property with a rifle that was already older than he was and told me that the rifle was a language and that to speak it correctly you needed to first learn to listen. He had a notebook he carried everywhere — small, spiral-bound, with numbers written in pencil and erased and rewritten so many times the pages were feathered from the pressure. He taught me to track wind by sound, by the way grass bent at different distances, by the temperature differential between shadow and sun-warmed stone. He taught me that a shot was the last word in a long sentence that had to be constructed perfectly before the trigger was touched.
He did not come home from the third deployment.
The rifle in the case over my shoulder had been his.
Sergeant Cole Vance was the unit's top-ranked marksman, and the entire way he occupied space on that tarmac communicated that he knew it and that knowing it was the primary organizing principle of his existence. He stepped forward before Lieutenant Morrison could finish the introduction, reached out, and took the case from my shoulder. He had not asked. He popped the latches — they were worn down to bare metal from years of use — and stared at the rifle inside.
Then he laughed.

Not a quiet laugh. A public one, designed to expand to fill whatever space was available to it.
"Did your grandpa leave this in supply?"
