3,000-year-old ancient Indian tech meets modern conspiracy against the backdrop of Mumbai in this bestselling urban fantasy thriller
Co-authored by Sheetal Choksi and Samiran Ghosh, the novel blends Sanskrit wisdom, futuristic tech, and Mumbai’s vibrant streets in a gripping young adult adventure.
MUMBAI, July 22, 2025:Thuldrun.Sunya has stormed into the literary world, debuting at #1 in Hot New Releases and Bestsellers in the Urban Fantasy category. Co-written by qualitative researcher Sheetal Choksi and technologist Samiran Ghosh—two-thirds of the award-winning 3 Techies Banter podcast—the novel redefines young adult fiction with a thrilling mix of mythology, science, and futuristic imagination.
The title draws inspiration from thorium, element 90, a silvery metal with immense nuclear potential found along India’s southern coast. It also references “Tula-Drona,” an imagined ancient Sanskrit phrase linking Dronacharya’s advanced knowledge from the Mahabharata to nuclear science. Adding a philosophical layer, śūnyā (the Sanskrit root of zero) symbolizes not just a number but a cosmic void of infinite potential—an intersection of science, philosophy, and spirituality.
A Thrilling Story Rooted in Mumbai
Set against the bustling streets of Mumbai, the story follows teenager Ansh Chatterjee—a conspiracy nerd and Maggi addict—who stumbles upon a secret that challenges historical narratives and awakens a 3,000-year-old destructive force.
Imagine cities powered by thorium cores, Sanskrit equations glowing across holographic walls, and a civilization that chose science over sorcery—peaceful, powerful, and possibly interstellar. The book challenges the notion that ancient humans were merely hunters and gatherers, hinting at a forgotten technological golden age.
Even the city itself plays a pivotal role. As the authors hint, the cracks on Dadar’s pavements might not be just civic negligence—they could be fractures in spacetime, remnants of something the universe tried to erase.
The Creators on Their Vision
“The past doesn’t need resurrection—it needed translation. We explore the intersection where India’s pracheen wisdom meets modern technological possibility,” says co-author Samiran Ghosh.
Sheetal Choksi adds, “Podcasts are just books waiting to happen. We turned our mythology-versus-science debates into literary jazz.”
What Readers Are Saying
Readers have praised the novel for its fresh approach and vivid storytelling:
“The city isn’t just a setting—it’s a living, breathing character.”
“You can picture the streets, the people, the energy. It’s gripping without feeling clichéd.”
“A thrilling mix of tech, sci-fi, and mythology set in the heart of Mumbai, with surprising twists—including a chapter from a dog’s perspective!”
With an infinity symbol subtly hinting at more to come, Thuldrun.Sunya may just be the start of a larger saga.
