Hello!
I would now like to tell you about an Interlinear book of Kafka, which could help you practice your German.
Interlinear books are such where the translation follows below each word or expression in the original text. This lets you to understand a book in German without a dictionary.
InterlinearBooks.com has released a number of such Interlinear books since late last year, including Swedish, Lithuanian, and now - also German.
You can get the German translation here:

If you are interested in getting some German reading practice, do have a look at it!
Good luck!
