Who is Kapu's mother?

Kapu’s mother is Silver. Kapu and her mother are wolves. Their names are given to them by Miyax, who has lost her way on the northern slopes of Alaska. Miyax is the daughter of Kapugen, a great Eskimo hunter. She loses her way after running away from her husband Daniel. It is then that she comes across a pack of wolves in a region covered by large amounts of grass and moss. She sets camp temporarily near the wolves with the aim of sharing their food. She names the adult wolves Amaroq, Silver, Nails, and Jello. Amaroq is the leader of the pack and Silver’s mate. Kapu is the leader of the five puppies. Miyax calls him Kapu after her father. She calls him this because she thinks that he is “smart and fearless,” just like her father.
