The Metamorphosis

"One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible vermin. He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked."

--Franz Kafka

"The Metamorphosis (German: Die Verwandlung, also sometimes translated as The Transformation) is novella, by Franz Kafka, first published in 1915. It has been cited as one of the seminal works of fiction of the 20th century and is studied in colleges and universities across the Western world. The story begins with a traveling salesman, Gregor Samsa, waking to find himself transformed (metamorphosed) into a large, monstrous insect-like creature. The cause of Gregor's transformation is never revealed, and Kafka himself never gave an explanation. The rest of Kafka's novella deals with Gregor's attempts to adjust to his new condition as he deals with being burdensome to his parents and sister, who are repulsed by the horrible, verminous creature Gregor has become."
