“We ignore the blackness of outer space and pay attention to the stars, especially if they seem to order themselves into constellations. “Common as the air” meant something worthless, but Hackworth knew that every breath of air that Fiona drew, lying in her little bed at night, just a silver flow in the moonlight, was used by her body to make skin and hair and bones. The air became Fiona, and deserving—no, demanding—of love. Ordering matter was the sole endeavor of Life, whether it was a jumble of self-replicating molecules in the primordial ocean, or a steam-powered English mill turning weeds into clothing, or Fiona lying in her bed turning air into Fiona.”
