My Daughter Went Missing from Kindergarten with Her Backpack*** 15 Years Later, It Arrived at My Door with a Letter That Began, ‘Mom, You Won’t Believe Who Took Me That Day’

It was raining when I saw the box on my porch.

At first I thought it was a delivery mistake. My husband, Daniel, said he had not ordered anything. Neither had I. There was no label. No sender.

I opened it.

Inside was a small pink backpack covered in faded silver stars.

It was Caroline’s.

I carried it inside like it might fall apart in my hands. Daniel kept asking what it was, but I could not answer. I unzipped it and found an envelope, one folded page, and nothing else.

The first line made my throat close.
