Otherwise Alone

Lieutenant Evan Arden sits in a shack in the middle of nowhere, waiting for orders that will send him back home - if he ever gets them. Other than his loyal Great Pyrenees, there's no one around to break up the monotony. The tedium is excruciating, but it is suddenly interrupted when a young woman stumbles up his path.
He has two choices - pick her off from a distance with his trusty sniper-rifle, or dare let her approach his cabin and enter his life.
Why not? It's been ages, and he is otherwise alone...
