I probably could have timed this post better, since it's about 9pm in Europe, but maybe our German speakers are night owls.

So once upon a time (about 10 years ago now), I could speak, read, and write German fairly well. Now I'm out of practice, but I don't want to lose the language completely. Do you have any book recommendations for me that are interesting and not super difficult but still challenging... Maybe something along the lines of Harry Potter or The Hunger Games wenn es so etwas auf Deutsch gäbe?

Tausend Dank!
