Shauna lay sprawled across her bed, the soft hum of a ceiling fan filling the silence. The summer night air was warm, and the open window let in the occasional cool breeze.

Shauna’s mom, Debbie, was working the night shift at the hospital, leaving the two girls to enjoy their time together uninterrupted.
