I had been a night nurse at Lincoln County Memorial Hospital in Nebraska for thirty-two years, and I thought I had witnessed every shade of human suffering. But nothing—nothing on God’s green earth—prepared me for the sight of that little boy.

It was three in the morning on a bitter December night, the kind of cold that seeps through the walls and settles in your bones. The emergency room was quiet, just the hum of fluorescent lights and the distant beeping of monitors. I was sipping lukewarm coffee at the nurses’ station when the automatic doors slid open with a soft, mechanical hiss. A gust of freezing air swept in, and with it, a silence so heavy you could feel it pressing on your chest.
