Abrupt Mutations leads the reader on a humorous, meandering tour of 1960s Megalopolis, at the heart of which is a hotly anticipated gathering of the city's culturati at the home of O Jango, a Brazilian billionaire and aesthete equally revered and reviled by his fellow Megalopolitans. Parodying a number of literary styles, including the detective novel and science fiction, Revol's novel is first and foremost a Menippean satire of the cosmopolitan west in the sixties, detailing hilariously but humanely the lives of intellectual and artistic emigrees who have fled from dictatorships and found in their adopted city opportunities for personal freedom and pleasure they previously could never have dreamed of.
