Count Hamnet Thyssen is a minor noble of the drowsy old Raumsdalian Empire. Its capital city, Nidaros, began as a mammoth hunters' camp at the edge of the great Glacier. But that was centuries ago, and as everyone knows, it's the nature of the great Glacier to withdraw a few feet every year. Today Nidaros is an old and many-spired city; and though they still feel the breath of the great Glacier in every winter's winds, the ice cap itself has retreated beyond the horizon.
Trasamund, a clan chief of the mammoth-herding Bizogots, the next tribe north, has come to town with strange news. A narrow gap has opened in what they'd always thought was an endless and impregnable wall of ice. The great Glacier does not go on forever - and on its other side are new lands, new animals, and possibly new people.
Ancient legend says that on the other side is the Golden Shrine, put there by the gods to guard the people of their world. Now, perhaps, the road to the legendary Golden Shrine is open. Who could resist the urge to go see? Not Hamnet Thyssen or Trasamund. Not Ulric Skakki, Hamnet's old comrade in arms: a good man to have at your side, although perhaps not at your back. And not, damnably, Eyvind Torfinn - a scholar, a very knowledgeable man but, alas, the husband of Hamnet's former wife, Gudrid: a troublemaker if there ever was one. She's decided to come along, too.
For every one of them, the Glacier has always been the boundary of the world. Now they'll be traveling beyond it into a world that's bigger than anyone knew. Adventures will surely be had...
