On the unforgiving Arctic Ice . . . United once again, Toklo, Lusa, Kallik, and Ujurak continue across the ice. Conditions are harsh and especially treacherous for the black bear and grizzly bears who are not used to the brutal cold, never-ending snow, and limited food. But the bears are certain now that they're on the right course, and with the stars still guiding them, they push forward. When they reach land at last, the group is overjoyed, but something is not right. The bears who live here are ill. What's wrong with them? What can the foursome do to help? Is aiding these strangers the ultimate goal of their quest? Ujurak just might hold the key to their mission in his paws, yet it's Lusa the new bears are especially interested in. Three young cubs, each from different backgrounds, and their mysterious shape-shifting companion have grown up together in their long and dangerous journey to save the wild. Now, when their task appears more difficult than ever, the bears must make a critical decision . . . and for one bear the path ends here.
