In spurts and bursts and flashes, a sublime novelist at work reveals herself. In Annie Proulx’s new novel, there are breath-taking pages and set pieces of extraordinary power. A man on board a ship, as the temperature plummets, sees all those around him embedded in ice before the catastrophe falls on him; a logging run down a river blocks, builds and explodes with the force of missiles; a wall of fire sweeps across a forested wildness.
