From the moment Elena Brooks arrived on the training grounds at Fort Kingston, the other recruits behaved as if she had somehow wandered into the wrong place. She was too calm, too quiet, and far too disciplined for what they expected from someone who had just entered boot camp. One recruit called across the field. “Hey, princess! Did you forget your tiara at home?” Laughter rolled across the training area, but Elena gave them no reaction. She ignored the jokes, ignored the endless teasing, and remained silent even when one recruit reached toward her boot during the mud crawl, trying to slow her down. Elena simply continued forward.
