Mission of Revenge — Edison Marshall

Young Angus MacKenzie went to Narwhale Bay to rectify a sin committed by his father, who died before revealing his secret. But on meeting Ugruk, the mighty, half-breed hunter, he understood his father's anguish. Ugruk was his half-brother.

Emil Konrad, a cruel, strong materialist proposed to drive Angus from Narwhale Bay, but found his way barred by his beautiful, passionate daughter Gretchen, who fell in love with Angus.

Konrad is killed in a fight, and Angus, Gretchen and Ugruk flee over the ice to a deserted prospector's cabin, and marooned in the bleak and desolate north country, these three played out the drama of life and death.
