Riverhead will publish Hernan Diaz‘s next novel, PLY, on September 29, the AP reports. The book is “a futuristic thriller in which a young orphan survives by stealing electricity from the grid and selling it on the black market.” “After rewriting America’s past with his two previous novels, Hernan Diaz now gives us a glimpse into the future,” Riverhead said in a statement. “‘Ply’ questions the place of technology in the American experiment with a plot that grabs both heart and mind.”
