John Irving 
World According To Garp [EPUB ebook] 

This is the life and times of T. S. Garp, the bastard son of Jenny Fields – a feminist leader ahead of her times. It is also the life and death of a famous mother and her almost-famous son; theirs is a world of sexual extremes – even of sexual assassinations. It is a novel rich with 'lunacy and sorrow’; yet the dark, violent events of the story do not undermine a comedy both ribald and robust. It provides almost cheerful, even hilarious evidence of its famous last line: "In the world according to Garp, we are all terminal cases."
