I will never forget the sound of my stepmom collapsing in her kitchen.

It was a Tuesday morning in Charleston, the air already thick with August humidity. I had stopped by her little house on Magnolia Road to bring her a fresh loaf of banana bread. She was standing by the sink, humming an old Patsy Cline song, when her body suddenly went rigid. The coffee mug slipped from her hand and shattered on the tile floor.
