The heat at Red Bluff Training Depot, somewhere in the barren outskirts of El Paso County, felt like a physical force. It clung to the skin, crawled beneath fatigues, and turned the morning into a trial before the day even began. The sun rose early there, dragging a curtain of white glare over the concrete and chain-link fences. The air smelled of hot metal and scorched sand, and the wind carried grit that gathered in your teeth if you dared open your mouth.

I was known as Private Peyton Winslow, twenty-six years old, allegedly from a little place in rural Arizona that no one could find without squinting at the map. I dressed like someone who had never quite fit anywhere. My boots were laced unevenly and my bun was regulation length but messy enough to invite scolding. I kept my gaze low and my movements timid because that was the assignment.

Inside, beneath the quiet persona, I was someone else entirely. My real name was Lieutenant Colonel Celeste Navarro, United States Army Military Intelligence. I had served overseas, facilitated covert extractions, and spent a decade studying how power rots from the inside when no one is watching. At Red Bluff, no one saw me as anyone worth noticing, and that was the greatest advantage I had.

Training began at six. By five-thirty we lined up in the barracks courtyard, sweat already soaking through our undershirts. Private Lila Durant, barely nineteen and fresh out of high school in Arkansas, nudged my arm gently.

“Peyton, you need to hurry,” she whispered with a tremor in her voice. “First Sergeant Briggs is looking rough this morning. Rougher than usual.”
