The good part that this book surprised me again. In Feb 2020 I've read book by Mykola Khvylovy. This one one similar - same generation of Ukrainian authors during the early days of Soviet Union.
Topic was modern, language was modern.
What I didn't like was the main character. I don't even understand if author likes him or not. He confused me.
Maybe that is the whole point? Are all of us unlikable? No, proper heroes and characters in real life. Just random creatures, with random feelings and decisions and actions.
