The book has evolved from being a request for the West to provide quality mental health service support to a traumatised nation into an equally urgent plea to allow Ukrainians to speak for themselves in determining their future. 

‍Diary of a Volunteer is a non-commercial book not available for purchase. It exists in two forms. The first is as an Edition of One, a unique, oversized dummy that Neville made by hand in Kyiv that has been circulating in the UK among academics, actors, musicians, museum directors, politicians, writers and displaced Ukrainians since Autumn 2024. Neville says he made Edition of One "…in response to how the story of Ukraine is being told to the West through a saturated mass of online platforms, a swamp of digital noise that makes us unable to feel or think anymore and even less able to respond. By creating a photobook as a unique handmade object that can only be read and viewed by one person at a time, I can more meaningfully communicate our wartime experiences.."

In July 2025, we disseminated the second Diary of a Volunteer incarnation. The Activist Edition is 1,000 self-published copies of the book that we posted for free to targeted audiences in Ukraine, Europe, and the USA, those with the power to help shape public perceptions and behaviours in response to the war on Ukraine, to raise awareness of the opportunity we have to give Ukrainians a voice at this critical time. Each recipient of this edition - be they a celebrity or historian - also receives a personal written request to join a specialised circle of supporters for Ukraine. We do not request funding or money; instead, we mean to employ people's vision and talents.

As a result of Postcode Ukraine, Neville's relationship as an author with his subjects and audiences is transformative. People and their wartime experiences are not just represented for news outlets, nor are issues tokenly addressed for a photo and art market. Ukrainians are instead Neville's co-creators, and they benefit in tangible, life-changing ways quickly and effectively from his charitable aid visits. He says, "The people I encounter and photograph in frontline towns often directly benefit from that meeting and our discussions. Their courage inspires me to continue, and I try to reciprocate the best way I can. It's an experiment into the potential of photography when all elements of that art world support and contribute."
