The first children's book by Marc-Uwe Kling. This can't be true, can it? Grandma has broken the internet. And the whole thing. All over the world. Tiffany, Max, and Luisa can't stop being amazed, because nothing is working anymore. At first, it's quite funny. Suddenly, everyone has time. But then it becomes really cozy, even though the internet isn't working - or maybe that's exactly why. A workout for the family's laughing muscles.
