Kusinenkram und Kunforak

Freya and Sophie are the very best of cousins. They even have a cousin language that nobody else in the world understands. Sophie's older brother Johannes can pack his bags, as he only speaks Latin. No wonder he does everything he can to get his hands on the Kunforak - their top-secret dictionary.
Unfortunately, Sophie and Johannes don't live in the same town as Freya, so the two cousins only see each other during the holidays. To make the time in between not so long, they write letters to each other in which they plan how to get a little closer to faraway lands and real adventures - their ultimate goal! And even if things sometimes turn out quite differently than expected when they meet, what they experience must be documented and saved for posterity! Because nobody can make that up, it's the very best cousin stuff.
