On my long to-do list is to not only write the Gnomeville beginner French comics, but to also write a series in German and another in Dutch, both for which I have some preliminary drafts. Meanwhile, I have found an excellent beginner comic in German by Janine Wolf-Schindler. The illustrations are crude but effective, the language simple, and there are translations discreetly placed at the bottom of the page. This is now my recommended first read in German. That may change when I find (or write) other resources, but it is a good start.
I’ve yet to think about where this comic fits in the sequence of reading difficulty of available texts in German. There are ELI and La Spiga texts that are easy. After that there are teen readers, and various krimis. I’ll leave that analysis and discussion for another day.
