what type of author is he?

The style of the book epitomizes Kafka's writing. It was common for Kafka to present an impossible situation, such as a man's transformation into an insect, and develop the story from there with perfect realism and intense attention to detail. The style seems to ground the story in reality, cutting off any possibility of its having been a dream, and yet the story itself is of an impossible occurrence. As a result, the reader is forced to look for deeper meanings within the story.
