Silence was my sister's weapon. When people hurt or angered her, she never got loud like Mom or mean and smart-ass like me. Silence was how she fought back. It wasn't passive, or an act of helplessness: it was a cold cruel withering blade, lasting far longer than my mother's rage or my own antagonism, strong enough to make us practically beg for forgiveness every time. Except now her weapon had gone haywire, turned on herself, driven her from her home and her support system and into what-knew-what kind of danger.
