In Julie of the Wolves, our heroine has two heroes: Kapugen and Amaroq. Her father, Kapugen is a great Eskimo hunter, whom she admires for his faithfulness to Eskimo culture and his wisdom about surviving in the wilderness. She admires her adopted wolf-father Amaroq for the affection and loyalty he shows to his pack, and for the fact that he saves her life time and again. But the more you admire someone, the more devastating it can be to find out who he or she really is. It's much easier to admire from afar, in our memories, than it is to admire a flawed and real person, and Miyax is no exception to this rule. When she finally reunites with Kapugen at the end of the novel, she discovers that the man she worshipped for so long does not actually exist. Is there anything more heart wrenching than that?
The lesson of Julie of the Wolves is that we should not admire our heroes blindly, without criticism. We'll only end up disappointed.
Miyax's admiration for Kapugen and Amaroq is what keeps her alive on the tundra. Without them to admire, she may have died on her adventure.
