Hi! I made a post earlier asking for recommendations of novels in German. I just want to share an editorial named "Genua : Cideb Editrice" that helped me solve the issue. They publish novels dedicated to German learners, with definitions for difficult words in the foot notes, an adapted redaction for easy reading, and also with questions per chapter. I have been reading and enjoying the biography of Einstein, and I recently started "Die Verwandlung" by Kafka.
Here's a link for that last one on a database, so it is clear enough what I am talking about.
Tell me if you find it useful!
