“Go hide, Nurse. You’re limping—don’t make yourself a target.”

The words were meant as protection, but they landed like an insult in Camp Granite, a frozen training site tucked into the Montana mountains. Snow hissed sideways across the range, biting at exposed skin and swallowing sound. Kelsey Arden, nurse practitioner attached to a Marine winter package, nodded without arguing. She kept her shoulders rounded and her limp believable—because her cover depended on looking harmless.

She’d spent years practicing that limp.
