Once, Lacy had been present at the birth of an infant that was missing half its heart. The family had known their child would not live; they chose to carry through with the pregnancy, in the hope that they could have a few brief moments on this earth with her before she was gone for good. Lacy had stood in a corner of the room as the parents held their daughter. She didn't study their faces; she just couldn't. Instead, she focused on the medical needs of that newborn. She watched it, still and frost-blue, move one tiny fist in slow motion, like an astronaut navigating space. Then, one by one, her fingers unfurled and she let go.
