Ratha is a young herder of the Named, a clan of intelligent prehistoric wild cats who keep deer and horses. The Named fight for survival against Un-Named cats, enemies who raid clan herds. Meoran, leader of the Named, claims that the Un-Named are no more intelligent than herd animals, and Ratha believes him, until a clash with an Un-Named raider who taunts her in Named speech forces her to question everything. Then Ratha tames a power that could upset everything. Threatened by her discovery, the tyrannical clan leader banishes her from the clan. Can a young clan herder who doesn't know hunting, use her new "creature" to survive in exile?
