Bend Sinister by Vladimir Nabokov

The first novel Nabokov wrote while living in America and the most overtly political novel he ever wrote, Bend Sinister is a modern classic.  While it is filled with veiled puns and characteristically delightful wordplay, it is, first and foremost, a haunting and compelling narrative about a civilized man caught in the tyranny of a police state. Professor Adam Krug, the country's foremost philosopher, offers the only hope of resistance to Paduk, dictator and leader of the Party of the Average Man.  In a folly of bureaucratic bungling and ineptitude, the government attempts to co-opt Krug's support in order to validate the new regime.
