One afternoon many years ago, James Rebanks met an old lady on a remote Norwegian island. She lived and worked alone on a tiny rocky outcrop, caring for wild Eider ducks and gathering their down. Hers was a centuries-old trade that had once made men and women rich, but had long been in decline. Still, somehow, she seemed to be hanging on. Back at home, Rebanks couldn't stop thinking about her. She was fierce and otherworldly - and yet strangely familiar. Years passed. Then, one day, he wrote her a letter, asking if he could return. Bring work clothes, she replied, and good boots, and come quickly: her health was failing. He travelled to the edge of the Arctic to witness her last season on the island. Slowly, he began to understand that this woman and her world were not at all what he'd previously thought. What began as a journey of escape became an extraordinary lesson in self-knowledge and forgiveness.
