Book excerpt: His story begins with the arrival of his father, Howard Kantner, to the remote Arctic of the 1950s and ends with him as a grown man settled in the same landscape. Through a series of moving essays and vivid photographs, ranging in subject from family histories to hunting stories, celebrations of people and places to a lament over a majestic wilderness rapidly disappearing, Shopping for Porcupine provides a compelling, intimate view of America's last frontier -- the same place that captivated so many readers of Ordinary Wolves.
