She nodded solemnly, accepting the responsibility of memory as if it were a real object.

For one tiny startled second, General Thomas Hale, four-star officer, seemed unsure what to do with a small girl’s full-speed gratitude. Then he put one hand lightly on her back and closed his eyes.

When she let go, Sergeant Moreno stepped forward and saluted her again, less formal this time, almost playful. One by one, the others did too. Emma returned the salute with crooked seriousness, which made every grown man standing there look suddenly close to smiling and crying at once.

When I carried her inside, she stirred just enough to murmur, “Daddy sent friends,” and then slipped back under.
