The essential Kafka «Metamorphosis y the trial»

“One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible vermin...”
The Metamorphosis is a novella 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 repelled by the horrible, verminous creature Gregor has become.
During 1914, Kafka began the novel The Trial, the story of a man arrested and prosecuted by a remote, inaccessible authority, with the nature of his crime revealed neither to him nor to the reader.
