Assigned to the tightest bunk in the Marine barracks, the newest arrival quickly understands that his senior bunkmate holds more than rank over him. The sergeant's presence fills the narrow space between their cots, turning every order into an invitation the recruit cannot quite refuse.

Discipline becomes something else in the dark, where one man's command leaves no choice but to obey or cross a line that could end careers and shatter the rules they both live by. The recruit feels the weight of that authority settling over him with every shared breath.

The sergeant does not ask. He simply states what will happen next, and waits for the answer that will define them both.
