When the author and podcaster Viv Groskop first visited Ukraine, she travelled there from Moscow, on a long train that ran eventually beside a field of sunflowers. They were, she recalls in her lovely and modestly scaled memoir, like a ‘blast of sunshine screaming: “Welcome to Ukraine! You are no longer in Russia!”’

The year was 1994, and Groskop had been in the former USSR for a little under a year.
