Sister of the Sky — Margaret Allan

Out hunting rabbit, Green Eyes Blue is kidnapped by a merciless father-and-son team, traders from the distant city of Tollan. In trying to escape her captors, Green Eyes badly injures the father and permanently disfigures the son with an enchanted jade knife. She is saved by Lord Golden Hand, also of Tollan, who is instantaneously taken by the beautiful young virgin with the god-marked eyes. After killing the father and banishing the son from Tollan, Lord Golden Hand begins planning his marriage to Green Eyes. Meanwhile, unbeknownst to the lovers, the banished son returns to Tollan, seeking revenge for his father's death. Allan fuses interesting characters and prehistoric spirituality in this classic struggle between good and evil.
