My daughter disappeared when she was 10, and nothing in my life has ever been the same. Fifteen years later, on the exact anniversary of the day she vanished, a little girl was wheeled into my pediatric unit. She was the spitting image of my daughter. Nothing made sense until I saw her mother.My name is Helen, and there are two versions of my life: before my daughter, Anna, went missing. And after.She was 10 years old, and it was an ordinary Thursday morning. I packed her lunch, smoothed her hair down on one side the way she always let me, and kissed her cheek at the front door.Anna walked down the driveway, swinging her backpack, and she turned back once to wave. That was the last time I saw her.

By evening, Anna hadn’t come home. Her school was only a few blocks away, and she always walked, so at first I told myself she was just running late. But as time passed, the worry I’d been trying to ignore started to grow.The search went on for weeks and then for months. Investigators found Anna’s schoolbag near the grounds of the old cemetery, the place where her father had been laid to rest two years earlier.We believed she had gone there on her own to visit him, the way she sometimes did without telling me.ut beyond that, nothing. No trace. No answers.A few years later, the authorities officially declared her gone.I never accepted it. I kept looking in ways that made the people around me worry. I scanned the faces of strangers in grocery stores and on street corners.God, I was so convinced that someday the right face would be there.It never was. But I never entirely stopped.To keep myself from going completely under, I went back to school and became a nurse.Pediatric ICU, specifically, because someone had to be in those rooms standing guard for children who couldn’t stand for themselves.
