Simply complex

First introduction to Kafka that puzzled me. I did not know where to put myself in relation to his work. The problems are added to as and when the advance of life of K. And anxiety is growing, characters are gradually disappearing K. leaving only real protagonist of the book. A sometimes complex to understand writing, and yet we literally die when one is with the work and nothing author. The different information accompanying the preface are welcome to understanding the work and the novelist.
