The three chronological phases—denial, deliberation, and the decisive moment—make up the structure of this book. Real life doesn’t usually follow a linear arc, of course. Sometimes the path to survival is more like a looping roller coaster, doubling up and back upon itself as we struggle to find true north. So within each section you will notice that we often glimpse the other stages. There is, unfortunately, no single script in these situations. But it’s rare that anyone survives a disaster without pushing—or being pushed—through each of these three main stages at least once.
