At once a relentlessly fast-paced, admirably observed novel of social unrest and the story of a young man's struggle for identity, In Dubious Battle is set in the California apple country, where a strike by migrant workers against rapacious landowners spirals out of control, as a principled defiance metamorphoses into blind fanaticism. Caught in the upheaval is Jim Nolan, a once aimless man who find himself in the course of the strike, briefly becomes its leader, and is ultimately crushed in its service.
