In Harmonia, everything works.

The city is comfortable. The trains arrive on time. Nobody worries about money, work, healthcare or loneliness. Artificial intelligence has quietly removed most of life's difficulties, leaving humanity safer, healthier and better adjusted than ever before.

But something has been lost along the way.

Cian, a therapist living in this perfectly managed world, begins noticing the small imperfections that still survive beneath the surface: a woman who misses hesitation, a friend who refuses to take anything seriously, old songs that sound better because they aren't perfect, and people who still need each other in ways no system can fully understand.

Harmonia is a quiet literary science-fiction novel about technology, friendship, loneliness and the strange imperfections that make life feel human.
