David Winkler begins life in Anchorage, Alaska, a quiet boy drawn to the volatility of weather and obsessed with snow. Sometimes he sees things before they happen - a man carrying a hatbox will be hit by a bus; Winkler will fall in love with a woman in a supermarket. When David dreams that his infant daughter will drown in a flood as he tries to save her, he comes undone. He travels thousands of miles, fleeing family, home - and the future itself.
