The New Art of Living
Practical non-fiction for people who take their lives
seriously enough to design them.

The Publisher

Living well is a skill. We publish the books that teach it.

Nova Ars Vivendi is an independent publisher of practical non-fiction. The name is Latin for
The New Art of Living, and it captures what we believe: that living well is a skill, that the skill
can be taught, and that a well-made book is still one of the best ways to teach it.

We started with a conviction: that the best non-fiction books do not just explain the world.
They hand the reader the tools to change their part of it. Not with slogans, not with
inspiration, but with frameworks, protocols, and honest language that treats the reader as a
capable adult.

Our catalogue spans practical philosophy, relationships, later-life design, psychology, and the
thinkers behind it all. Five authors, each a specialist in their domain. The subjects vary widely.
What unites them is an editorial philosophy: evidence first, tools always, and no filler.
The Standard
We do not publish opinion dressed as expertise.
Our editorial process is how we enforce what we believe. Every book is researched before it is written, reviewed by multiple independent editors, and stress-tested against the needs of real readers before it goes to print.
If a book contains a framework, that framework has been tested. If it contains a script, that script uses the words real people would actually say. If it makes a claim, that claim is grounded in research.
We believe that living well is a design problem. It takes clarity about what matters, honest assessment of what is not working, and the willingness to build something better. Our books are the blueprints.
The Authors

Five voices. Five domains. One standard.

Alex Merrett
Marriage Maintenance Manuals
Alex Merrett
Alex Merrett spent a decade in counselling psychology before concluding that most couples do not need therapy. They need maintenance. Her Marriage Maintenance Manuals treat a relationship the way an engineer treats a bridge: with regular inspections, preventive care, and a clear protocol for when something cracks. She writes the way a trusted friend gives advice:directly, warmly, and without the jargon that makes most relationship books feel like a clinicalintake form. Each edition targets a specific marriage context, because the couple navigating anewborn's sleep schedule needs different tools from the couple rebuilding after a breach oftrust. The research is rigorous. The voice is human.
Gregory Sloane
The Intentional Years
Gregory Sloane
Gregory Sloane writes practical guides for designing the second half of life. His readers are systems thinkers, professionals, and introverts who are systematically underserved by books that tell them to "embrace the journey" or "find their tribe." Sloane treats life after fifty as a design problem, not a tragedy. His prose is architecturally precise: named frameworks, implementation protocols, concrete tools. Every chapter ends with a Minimum Viable System, the smallest version of the framework that still works, for the reader who is overwhelmed and needs one thing to do today. He does not tell readers what to think. He builds infrastructure and lets them decide.
Robert J. Hale
The One Hundred Pages
Robert J. Hale
Robert J. Hale studied natural sciences and philosophy at the University of Oxford before continuing his studies at the University of Leiden in the Netherlands. He then spent thirty years building businesses across Europe and Asia, discovering along the way that Marcus Aurelius was more useful in a boardroom than he had ever been in a lecture hall. Now in his early sixties, living in the English countryside, he writes books that do one thing well: take a great thinker's most important ideas and make them useful in one hundred pages. No jargon. No academic gatekeeping. Just the ideas that matter, explained clearly, with practical application for modern life.
Claire Langton
The Applied Self
Claire Langton
Claire Langton studied psychology in New York and cognitive science in Paris. After fifteen years in applied behavioral science, she grew tired of watching good research gather dust in academic journals while the self-help shelves filled with books that promised transformation and delivered platitudes. Her Applied Self series treats self-improvement as exactly that: a project. Each book takes one essential human challenge, applies a consistent five-part structure (Problem, Truth, Project, Blueprint, Future), and gives the reader an evidence-based plan they can actually execute. She writes for adults who are skeptical of gurus but serious about change, and who want science without jargon and plans without motivational noise.
Hendrik Deckers
Manuals of Life · Sketches of Life
Hendrik Deckers
Hendrik Deckers is an entrepreneur, scientist, and systems thinker. After leading a global digital leaders community, he turned to a quieter question: how do we live with clarity and purpose once the usual scripts no longer satisfy? He holds degrees in biology, philosophy, and economics. Science provides the evidence. Philosophy provides the questions. Experience provides the friction. His Manuals of Life are practical operating guides for adults who want to think clearly and shape a life that feels coherent rather than accidental. His Sketches of Life are something quieter: reflective essays born from walking, sleepless nights, and ordinary moments. He lives in Belgium with his wife and their dog Bess.

Every series has its own author, its own voice, and its own reader. A reader who finds value inone will find the same editorial standard across every book we publish.
Marriage Maintenance Manuals
by Alex Merrett
Most marriage books wait until something is broken. The Marriage Maintenance Manuals take a different approach: they treat a marriage like any complex system that works better with regular, intentional maintenance. Each edition targets a specific context, from new parents to dual-career couples to partners rebuilding after a breach of trust. Alex Merrett writes the way a trusted friend gives advice: direct, warm, and grounded in what the research actually says.

by Robert J. Hale

We are not a large publisher.
We do not aim to be.
We aim to be a trusted one.

When a reader sees our name on a book, we want that to mean something:
that the book was carefully researched, honestly written, and built to be
used, not just read.

We are building a catalogue, one book at a time. Each title earns its place.
