Penguin Modern Classics - One Flew Over the Cuckoo's Nest

Tyrannical Nurse Ratched rules her ward in an Oregon State mental hospital with a strict and unbending routine, unopposed by her patients, who remain cowed by mind-numbing medication and the threat of electroshock therapy. But her regime is disrupted by the arrival of McMurphy - who resolves to oppose her rules on behalf of his fellow inmates.
