I have posted a few times before about reading novels in a target language. I am recommending another group of books because they have helped me to stick to the habit better.
Hueber has this series of "Lesehefte" that contain short stories sorted by level difficulty.
What I like about them is that it is easier for me to stick to a complex reading in the format of a short story. They also have an appendix that clarifies difficult/rare words and a couple of exercises about the readings.
Right now I got lended "Das Wunschhaus" out of the library and it's also pretty comfortable to carry around. Give them a look if you are looking something like this :)
Also, I have many posts to related reading, so I may be doing a compilation about them on "logs". It may be more convinient.
