SOLVED. A German book about a boy who visits an unfamiliar region, ascends a mountain, finds a home near the top of the mountain, and befriends a girl living in the home. He eventually descends from the mountain and finds a riddle by the ocean shore. [s]

I read this book as a teenager, checked out from a city library in Bamberg, Germany.

I think the boy lives visits this region marked by fog and mild, but adverse weather with his parents, but soon abandons them, climbing up a mountain in the fog.

He stumbles upon a home in the thick of the fog, and befriends a girl in the house.

After he descends from the mountain, the reader finds him at a shore, and somehow the word Moixa, an anagram for Axiom figures into the story.

I never found that book again, but I remember a warm comfortable feeling reading it.

At the shore, possibly inscribed into a piece of stone or (drift?)wood, the boy finds the words MOIXA inscribed in an object.

This happens towards the very end of the book.

Found it! It is a novel by Dutch author Tonke Dragt and called "Die Türme des Februar" (The Towers of February).

Thank you so much, Sarah. I read this book forever ago, as a teenager, and it left such an impression on me, the intimacy of the setting, a mountain surrounded by fog. I will ask for this book at the library, and buy it, once I can. Tonke Dragt, that does ring a bell, but not more. I never would have guessed or found this book on my own. Thank you!
