The Metamorphosis

I really liked this short novel masterpiece by Franz Kafka (translation from original german) in its treatment of mutability of life, isolation, alienation through an absurd transformation of the protagonist into a monstrous beetle. Everything else that follows after this is portrayed with convincing logic and details. The shift in relations with the world, the self, the gradual indifference of people that constituted his world and his ultimate release are so well written. His work's said to be symbolic of travails in his own personal life. Some of the memorable phrases i liked -
'Just don't stay in bed being useless'
'Eating soon stopped giving him the slightest pleasure, so, as a distraction, he adopted the habit of crawling crisscross over the walls and the ceiling'
'Who in this overworked and exhausted family had time to worry about Gregor any more than was absolutely necessary'
'Was he an animal, that music could move him so'
'He would have announced this to everyone last Christmas-certainly Christmas had come and gone?'
'His conviction that he would have to disappear was, if possible, even firmer than his sister's'
