What was the first good event in Julie of the Wolves?
The first "good" event in Julie of the Wolves is most definitely when Julie comes upon the wolf pack. Before this, Julie is in a desperate situation because she has run away from her arranged marriage and has lost her way on the Alaskan tundra. As soon as Julie spies the wolf pack, she remembers what her father told her about wolves being our "gentle brothers":
Wolves are brotherly. ... They love each other, and if you learn to speak to them, they will love you too.
Remembering her father's wise advice, Julie begins to observe the wolves and try to figure out how she can get them to "love" her. First, Julie names the wolves. The leader is Amaroq. His mate is Silver. The leader of the wolf pups is Kapu (named after Julie's father, Kapugen). The sullen outcast is Jello.
By observing the wolves, Julie learns their behaviors. A nip on the top of the muzzle means dominance. Laying belly-up means submission. Flattened ears are friendly. Ears pointed forward mean aggression. Julie uses this knowledge to eventually become part of the pack.
