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 anti-capitalist 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.
