My name is Olivia Carter, and for thirteen years I believed I had an unshakable understanding of my daughter, Lily.After the divorce, it had been just the two of us in a modest, pale-blue house on a quiet street in a Massachusetts suburb where nothing ever seemed to happen.The kind of place where neighbors waved, lawns were trimmed on schedule, and secrets felt out of place.Lily was my constant. My certainty.She was thoughtful, mature beyond her age, and unfailingly polite. Teachers praised her. Neighbors admired her.She never raised her voice, never slammed doors, never asked for anything extravagant. In a world that had already taken my marriage apart, she felt like proof that I had done at least one thing right.

Or so I believed.That Thursday morning began like every other. Coffee cooling on the counter, my laptop bag slung over my shoulder, the familiar rush of being five minutes late. As I stepped outside, the crisp air brushing my face, I saw Mrs. Greene standing by her hydrangeas, her silver hair neatly pinned, her cardigan buttoned all the way up despite the mild weather.She lifted a hand, then hesitated, as if weighing her words.“Olivia,” she called softly, her voice carrying a strange caution, “is Lily not feeling well again?”I stopped short. “Not feeling well?”Mrs. Greene tilted her head. “Yes… she’s been coming home during the day. Quite often, actually. Sometimes with other children.”
