Hard Science Fiction

Bloodstone

A goddess. A signal. And mathematics!

Real number theory, geomagnetism, synchronization, and theories of consciousness become the machinery of a story rooted in Kamakhya and 7th-century Assam. Nearly 50 original illustrations make its hidden architecture visible.

From the Frankfurt Book Fair

“A hard science-fiction novel where number theory becomes signal, consciousness becomes physics, and myth becomes a form of evidence.”

The Premise

For centuries, Nilachal Hill has whispered to the rare few who can hear it — a low, impossible frequency that once reshaped a kingdom and left a girl suspended between matter and myth.

In the present day, an astrophysicist in Assam and an anthropologist with an inexplicable neural signature uncover a pattern buried in that ancient signal, one that echoes the mathematics Ramanujan claimed a goddess showed him. Their discovery draws the attention of forces who have been waiting — patiently, and with purpose.

Across continents, a failed writer, a grieving physicist, and a classified operation converge on a single event designed to push human consciousness past its threshold. What happens there will determine whether the signal remains a secret, a weapon, or reveals something far older than civilisation.

BLOODSTONE is a novel of hidden mathematics, ancestral memory, and the thin membrane between minds — where a goddess may be nothing less than the universe remembering itself.

The Science Inside Bloodstone

One signal. Many receivers.

Beneath the temple of Kamakhya, the hill itself hums — a faint, steady pulse that instruments can actually measure. In the novel, that hum is treated as a real signal: one that a few extraordinary minds across history — Riemann, Ramanujan, Bose — seemed to pick up long before any machine could explain where it came from.

Minds can get sychronized. A thought may be a pattern that can travel. And every one of these ideas is a piece of the puzzle the characters must solve!

The Story

Two timelines. One hidden legacy.

7th-century Kamarupa · Present-day Assam and Frankfurt

Spanning thirteen centuries — from an ancient sacrifice on Assam’s Nilachal hill to a high-stakes modern crisis — this gripping thriller follows anthropologist Ananya as she becomes the key to an unprecedented global discovery. Hunted by a shadow agency and racing against a reckless physicist whose actions threaten global catastrophe, Ananya — aided by her ally Aarav — must unlock a centuries-old legacy hidden within the earth before time runs out for humanity.

Author

Shamit Bagchi

Frankfurt-based author with a master’s in Applied Physics, an MBA, and deep AI strategy expertise. Bloodstone is his attempt to fuse the mathematical structures he studied with the mythic history of Assam.

Artist

Charbak Dipta

Kolkata-based illustrator whose nearly 50 original pieces for Bloodstone translate Tantric iconography and abstract mathematics into a singular classical-meets-contemporary visual language.

In Conversation with Cixin Liu

A lineage of uncompromising science fiction

Bloodstone stands on its own scientific architecture. Its kinship with The Three-Body Problem lies in the same wager: that rigorous science and a specific cultural history can enlarge each other.

01

Science as narrative engine

The Three-Body Problem

Liu Cixin uses real astrophysics and game theory to structure Three-Body’s plot.

Bloodstone

Bagchi — an applied-physics master’s and AI expert — uses the actual 196,883-dimensional representation of the Monster group as literal cosmological architecture, not metaphor.

02

Illustration as a second narrative layer

The Three-Body Problem

Wu Qingsong translated Three-Body’s abstract science and VR-game surrealism into sequential art rooted in Chinese painting tradition.

Bloodstone

Charbak Dipta renders Kamakhya’s Tantric visual language and the novel’s mathematical cosmology through a classical-meets-contemporary Indian aesthetic.

03

A national epic wearing genre clothes

The Three-Body Problem

Three-Body is inseparable from Chinese 20th-century history.

Bloodstone

Bloodstone is inseparable from a specific Indian lineage — Kamarupa, Kamakhya, Assamese Tantra — treated with the same rigor Liu Cixin gave Chinese history.

04

Global potential

The Three-Body Problem

Three-Body’s illustrated edition moved from Yilin Press to German and Spanish markets.

Bloodstone

Bloodstone launched via Notion Press with the same cross-market shape: a book whose visual and conceptual hook travels independent of language.

Indian mythology meets the raw might of mathematics and physics. The Monster group, the Riemann zeta zeros, and a measurable 6.2 Hz geomagnetic pulse beneath Kamakhya — woven into the living mythology of Assamese Tantra and 7th-century Kamarupa.

Where the goddess is a signal and the signal is pure number, Bloodstone proves that ancient Indian cosmology and frontier physics can speak the same language.
