La metamorfosis

Metamorphosis (German: Die Verwandlung) is a novella written by Franz Kafka which was first published in 1915. One of Kafka's best-known works, Metamorphosis tells the story of salesman Gregor Samsa, who wakes one morning to find himself inexplicably transformed into a huge insect (ungeheueres Ungeziefer, lit. "monstrous vermin") and subsequently struggles to adjust to this new condition. The novella has been widely discussed among literary critics, with differing interpretations being offered. In popular culture and adaptations of the novella, the insect is commonly depicted as a cockroach.
