Realistic Portrayal of Future Technology
What the science actually says — on AI, drones, biotech, and what comes next. Grounded, technically literate, and built for audiences who want clarity rather than hype.
Some worlds refuse to stay in dreams. They wait until you are ready to write them down.
Shivang Ajay Desai is a serial technology entrepreneur, coder, and global keynote speaker based in London. Over two decades, he has built and exited multiple ventures across drones, health-tech, and deep-tech — the kind of career that requires equal parts vision and the willingness to rebuild from scratch when the vision demands it.
The world of Halo of Ashes did not begin at a desk. It arrived in 2013 as something closer to a fever dream — vivid, insistent, and entirely unwilling to be forgotten. Shivang carried it for years before the writing began in earnest in 2019. Life intervened, as it always does, and the manuscript waited with the patience of something that knew it would eventually be finished. He returned to it in 2026, and the book is what that long conversation between a man and his own imagination finally produced.
Away from the page and the podium, Shivang is a licensed skydiver and scuba diver, a former MMA competitor, and a person for whom the phrase up for a challenge is a governing philosophy rather than a personality trait. He holds a long-standing and serious interest in metaphysics and the nature of consciousness — the questions that live beneath the ones science has learned to answer.
He lives in London with his wife and an unreasonable number of gadgets.
The Grimknot Chronicles · Book One
#1 Amazon Bestseller: Dark Fantasy Horror | Military Fantasy
He woke to cracked earth and a red sky and nothing else. No name. No past. No understanding of why his hands, when he held them up against that strange, blood-coloured light, left scorch marks on the air around them. The world did not explain itself. It simply waited, the way ruin always waits, to see what a man would do next.
Four hundred years ago, the world ended. What survived is stranger and more dangerous than what was lost. A man wakes in the ruins of a dead civilization with no memory, no name, and something ancient living inside him — and must decide whether a world that destroyed itself deserves to be saved again.
A post-apocalyptic grimdark fantasy for readers of Joe Abercrombie, Brandon Sanderson, and Robin Hobb.
What the science actually says — on AI, drones, biotech, and what comes next. Grounded, technically literate, and built for audiences who want clarity rather than hype.
Being a technologist who writes dark fantasy is a strange existence. How entrepreneurs and creators can mine their own history for the authenticity that separates remarkable work from competent work.
How the storytelling instincts that make great fiction are the same ones that build companies people believe in.
Fast paced with a compelling narrative arc and complex, well thought out world building. And on top of that - it's beautifully written with an interesting, fully developed cast of characters.
Dark, haunting, and deeply immersive, Halo of Ashes stays with you long after the final page. Desai doesn't simply create a world, he gives it the weight of forgotten history, myth, and loss.
For fans of Abercrombie's moral complexity and Sanderson's worldbuilding depth, this is the kind of debut that makes you immediately want to know when Book Two is coming.
For speaking enquiries, media requests, rights and adaptation discussions, or simply to say that the book kept you up until three in the morning — Shivang reads everything.
