Vladimir Nabokov 
Bend Sinister [EPUB ebook] 

The state has been recently taken over and is being run by the tyrannical and philistine ‚Average Man‘ party. Under the slogans of equality and happiness for all, it has done away with individualism and freedom of thought. Only John Krug, a brilliant philosopher, stands up to the regime. His antagonist, the leader of the new party, is his old school enemy, Paduk – known as the ‚Toad‘. Grieving over his wife’s recent death, Krug is at first dismissive of Paduk’s activities and sees no threat in them. But the sinister machine which Paduk has set in motion may prove stronger than the individual, stronger even than the grotesque ‚Toad‘ himself.
