In his recent ClimateCultures post, Rod Raglin casts doubt on the claims of thrutopian fiction to set out a roadmap to a better future — “writing our way to a future we’d be proud to leave to the coming generations”, as thrutopian champion Manda Scott puts it. In his article Rod sets out the practical, political and economic realities that would need to be addressed before we have any chance of a better future. Many of these seem intractable and the charge levelled at the thrutopian fiction produced so far is that it fails to address these. Another charge is that when it tries to, it comes across as “more didactic than entertaining.”
Rod is right that it is very difficult to write fiction that is both entertaining and will raise awareness of climate policies that are likely to work and/or inspire more sustainable behaviours. I know because I have tried it.

Thrutopian fiction — changing behaviours
The first draft of my novel Habitat Man was appalling — everything I wanted the reader to know went in and it was didactic and clunky. I needed to write it then edit it out, just to get it out of my system. But by the final draft, I believe I pulled it off. An award-winning radio drama writer liked it so much she asked to put it in for a BBC Radio 4 adaptation and it got to the final round. It was the best seller in my bookshop for two years and reviews on Amazon are genuine and enthusiastic. In terms of behaviour change, research found that of 50 readers surveyed one month after finishing the book, 98% had adopted more pro-environmental attitudes and 60% had adopted at least one of the green alternatives mentioned in the book. These ranged from simple things like home composting and wildlife-friendly gardening, to campaigning. You can see the results in a link in the notes below.
Another novel, Visco, winner of the 2020 Green Stories novel competition sets out a quite plausible means by which a new society emerges from an old one. David Fell, himself a sustainability consultant, tells the story of a music festival on a small island within the UK that sets up a side festival for those who need care and their carers as part of an inclusivity drive. When the music ends, no one wants to go home and so they don’t. Step by step and overcoming one challenge after another, a more sustainable community based on the values of care emerges, attracting even the wealthy and powerful to its cause. Importantly, it’s also a damn good read!
I would claim that every story in the anthology No More Fairy Tales: Stories to Save Our Planet is thrutopian fiction. Several have been expanded into other forms. For example, one story imagined the ocean being given nation status and was developed into the novel Fairhaven, written by chemical engineer Steve Willis and writer Jan Lee. This sets out in fiction form a roadmap to how Malaysia could mitigate and adapt with respect to climate change.
The Philosopher and the Assassin: the evolution of a work
Another short story in the anthology was written as a standalone novella The Assassin, which is available also an audio book and as a play, Murder in the Citizens’ Jury. It imagines eight people in a citizens’ assembly debating climate solutions. The whodunnit element provides the drama and mystery. The context raises awareness of this emerging form of participative democracy, which I believe is an essential first step to real change. It also allows climate policies to be explored from the perspective of a variety of people, each of whom relates to them in different ways. Murder in the Citizens’ Jury was performed in 2024 in a sellout run, and later, a school put on an abridged one-hour version. It was interactive and the audience voted for their favourite climate policies. The director told me people were still debating the ideas days later. You can see reviews, details and feedback at the Green Stories link in the notes below.
Professional theatre companies can access it via Lazybee scripts, but it’s available royalty-free for any school/college drama groups and amateur theatre companies to stage if they approach me direct.

Inspired by the success of the theatre production, and wanting to reach a larger audience, I’ve included the ideas from the play as a story within a story in a novel, which was published by Habitat Press on 1st October: The Philosopher and the Assassin. A script version won the 2024 Writing Climate Pitchfest, and it is literary fiction: think campus novel meets moral philosophy meets murder mystery! The goal is thrutopian — it aims to entertain and suggest some of the key leverage points that could tip us in the direction of a sustainable future. Here is a brief description:
There’s no more important job in the world than educator, and no subject as necessary as moral philosophy. The trick is getting the students to turn up. So, when the Dean proposes the controversial concept of education entertainment, Professor Iris Tate goes all in with a moral philosophy course based on a whodunnit that all assume is hypothetical — a murder in a citizens’ assembly on climate. A variety of characters provide an entertaining source of ethical dilemmas, but what the students don’t know is that the ultimate dilemma is very real, and their conclusions will have far-reaching consequences.
Reviews so far have been reassuringly positive:
“At once a commentary on the looming responsibility of the climate crisis and our ever-shrinking opportunity to enact meaningful change, and a far from conventional whodunnit, the book plays with the notion of what is moral and what is right. Complicit in the book’s central sprawling philosophical dilemma, the reader finds themselves judge, jury and executioner in the case of the century. While the novel tackles prescient and troubling themes and poses difficult questions (how far should we go for the greater good?), it does so with a sense of dry humour and a delightful eye for the absurd. Above all, the warmth and resilience of its ineffable protagonist suffuses the narrative and, as the story ends, we struggle to leave her behind. Not only is this a timely, thought-provoking and essential story in an age of urgent, innovative climate action that demands the attention of us all, it is a thoroughly enjoyable read. Funny, memorable, characterful and original.”
— The Literary Studio
“Denise Baden’s campus novel/whodunnit is so much more than just an up-to-the-minute academic locked-door mystery, it’s a philosophical treatise wrapped in an exposition of the polycrisis, embedded in a love story, threaded through with alternative democracy and grounded in explorations of grief, motivation and drive. Full of sharp ideas, subtle humour and grounded in the harsh realities of our world, you’ll come away with a whole new understanding of our world and what it takes to change it!”
— Manda Scott, author of Any Human Power and Boudica series.
“If facts are ignored, fiction may be our next best hope. With its story-within-a-story, The Philosopher and the Assassin cranks up the dramatic tension around whether we will achieve the carbon transition, or not. Ultimately, a surprisingly hopeful read.”
— John Elkington, author of Tickling Sharks: How We Sold Business on Sustainability
“A sharp, witty take on the climate crisis – from someone who knows what they’re talking about.”
— Wren James, founder of the Climate Fiction Writers League

In his ClimateCultures post, Thrutopian Fictions: Ways to a Better Future?, fellow writer Rod Raglin asks if thrutopian fiction’s solutions-focused approaches to our climate predicaments address the real challenges: how to overcome our reluctance to make the sacrifices needed to get through the hardest times and towards a better future?
