The shack’s tin roof had leaked for two years straight, ever since we’d found the place.

Mama used to say it was the sound of angels knitting, the pitter-pat of raindrops in our little tin church. She could make any hardship sound like a blessing. That was her gift.

I thought of her as the blackest thundercloud rolled over the Tennessee hills and shook the ground. I was seven, maybe the only soul on County Road 12 that night without a real roof or a warm supper.
