The space between the family in the photograph on my dresser and what became of it is gaping and largely unknowable. My parents rarely spoke of each other. They rarely acknowledged that the family in the photograph ever existed. My father died before I was old enough or brave enough to ask him all my questions about the end of our family. Once or twice, we stumbled onto the topic, but those conversations were terse and awkward. I worried that he would take my curiosity for ingratitude, that he would think the life he had given me was not enough. My mother, when we were still speaking, would reveal only scant details. I did not push her. Our relationship was too fragile. And, always, below us, vibrations moved through solid rock.
