The Border — Kim Fielding

Injured in a war that has stretched on for years, Sergeant John Peterson guards a lonely border. Aside from passing contact with railship captains, the only person he sees is the enemy: the man who guards the other side of the border. A bad fall places John's life in the other soldier's hands. He's wary of his rescuer, First Lieutenant Thomas Fellowes, but over time he finds himself drawn to his new companion. Both soldiers carry the war in their souls, but they might find peace in each other.
