As other reviewers have already said: it is a truly gentle, hopeful, beautiful story about connection and self discovery and communication. It's got a post capitalist, solarpunk vibe of a world I'd love to inhabit, an appreciation for little pleasures and little deals, loveable characters, and it's also insightful and wise. Plus the main character rides a bicycle as their main form of transportation!
I now want to leave it all and become a wandering tea monk with a bike. That's how perfect this book is. Loved it.
