I thought the hardest part of the day was already behind us. Then my nine-year-old son called for me. What I noticed changed everything.

The father’s face went white before mine did.

I had felt plenty of swollen lymph nodes, abscesses, spasming muscles, and fractured faces in an ER.

That was not what frightened me.

What frightened me was the way the lump beneath my son’s jaw moved away from my fingertips.

Not with his pulse.

Not with his swallowing.

Something underneath the skin had shifted on its own.

“Ethan,” I said quietly. “Look at me.”

My nine-year-old son raised his eyes.

He had been crying so hard that his lashes were stuck together.

Beside him, my husband, Marcus, still had one hand wrapped around Ethan’s wrist.

“Fix him fast,” Marcus repeated. “I’ve got a shift.”

I looked at his hand.

“Let go of him.”

Marcus frowned.

“What?”

“His wrist.”

“I’m keeping him still.”

“You’re hurting him.”

He released Ethan immediately.

The skin where his fingers had been was already red.
