The air left my lungs. Every parent who had stayed for the party turned to stare, their conversations dying in their throats. Every child stood frozen, their half-twisted balloon animals dropping to the grass. And there, in the center of this sudden, silent hurricane, was my eight-year-old daughter, Meadow. She was wearing her special purple birthday dress and a crown of silk roses I had made by hand the night before. I watched, helpless, as her face transformed from radiant joy to a look of complete, shattering devastation.
