A turbulent novel, written in an intensity of realization of conflicts within man's relations to man. The setting is the Rockies (not far from Denver); the period the turn of the century; the theme, labor's struggle for a voice, with union organization coping with unscrupulous use of spies, good squads, Negro scabs; with playing both sides. The story concerns chiefly Dal MacNair and his conflict as he tries to play a part in the miner's battle, while finding a place for himself in the world of the operator's sister, Kathryn. against his passion for Kathryn deepening love for Fai, brought up as virtually a sister. Dal seems to betray his log he gets involved in suspicion of murder; when he is exonerated, he goes away to study and then puts it to use against his friends. Eventually, the power of the cause wins him again -- but it takes tragedy and loss to bring Fai and Dal together...There is compelling force to the story, but it is uneven in the telling, confusion engendered by too many ramifications, too unfocussed a cast of characters. But throughout burns the vitality of kinship among workers. Not for all readers.
