A narrator and her dog are criss-crossing the Swiss Alps. She travels with friends who share her interest in food, languages and their topographical contexts. They collect colours, even look for colourlessness, and develop the idea of a walk-in diary, a vain attempt to archive their observations. Gradually, other mountains appear in their observations and memories, as do the mountains of literature and art. Mountains may be sites of fear and awe, of narrow-mindedness, racism and ever-looming collapse; Alpine lodges may be places of hospitality, retreat and unexpected encounters; of nature under threat. In 515 notes, Zsuzsanna Gahse unfolds a finely woven interplay between her six characters while giving us a vivid panorama of mountain worlds, a multi-layered typology of all things mountainish.
