Perhaps most well-known today as the inspiration for Paul Thomas Anderson´s film There Will Be Blood, Upton Sinclair´s novel Oil! burst into the literary limelight amid soaring petroleum profits and gaping inequalities in 1927. By turns an ardent family saga, scintillating potboiler, and anticapitalist tirade, Oil! ranks among the most important critiques of fossil energy ever printed; and while anticipating how fossil fuels have shaped the dilemmas of our present, it also looks toward a greener, more inclusive, and altogether more livable world yet to come. This edition features a contextual introduction by Michael Tondre will illuminate the novel´s urgent timeliness in our warming world.
