Pack (canine)
Animals which typically predominate over others are associated with the term "alpha". Among pack-living wolves, alpha wolves are the genetic parents of most cubs in the pack. Such access to mating females creates strong selective pressure for intra-sex competition.
Julie (George novel)
Julie returns to the wolf pack and witnesses a new cub, whom she names Amy after her pen pal in San Francisco. Throughout the story, Julie learns to reconcile the old ways with the new, while struggling to protect her wolf pack.
