From bestselling author James Raffan comes an enlightening and original story about a polar bear''s precarious existence in the changing Arctic, reminiscent of John Vaillant''s The Golden Spruce.

Nanurjuk, '';the bear-spirited one,'' is hunting for seals on Hudson Bay, where ice never lasts more than one season. For her and her young, everything is in flux.

From the top of the world, Hudson Bay looks like an enormous paw print on the torso of the continent, and through a vast network of lakes and rivers, this bay connects to oceans across the globe. Here, at the heart of everything, walks Nanurjuk, or Nanu, one polar bear among the six thousand that traverse the 1.23 million square kilometers of ice and snow covering the bay.

For millennia, Nanu''s ancestors have roamed this great expanse, living, evolving, and surviving alongside human beings in one of the most challenging and unforgiving habitats on earth. But that world is changing. In the Arctic''s lands and waters, oil has been extractedand spilled. As global temperatures have risen, the sea ice that Nanu and her young need to hunt seal and fish has melted, forcing them to wait on land where the delicate balance between them and their two-legged neighbors has now shifted.

This is the icescape that author and geographer James Raffan invites us to inhabit in Ice Walker. In precise and provocative prose, he brings readers inside Nanu''s world as she treks uncertainly around the heart of Hudson Bay, searching for nourishment for the children that grow inside her. She stops at nothing to protect her cubs from the dangers she can seeother bears, wolves, whales, human beingsand those she cannot.

By focusing his lens on this bear family, Raffan closes the gap between humans and bears, showing us how, like the water of the Hudson Bay, our existenceand our futureis tied to Nanu''s. He asks us to consider what might be done about this fragile world before it is gone for good. Masterful, vivid, and haunting, Ice Walker is an utterly unique piece of creative nonfiction and a deeply affecting call to action.
