Rahul built GEOMAPSE during what was meant to be an eighteen-month data fellowship at NASA's Ames Research Center in Silicon Valley. The system fuses datasets that were never designed to talk to each other: space-weather feeds, geomagnetic readings from orbital satellites, ground-conductivity models, decades of legacy airborne surveys, even ley-line and temple-alignment overlays he added half as a private experiment. Most days GEOMAPSE does exactly what it was built for, giving power-grid operators and satellite-navigation teams a sharper map of the planet's electromagnetic field.
A Science and Faith Thriller Novel That Refuses to Pick a Side
Most fiction makes you choose. The scientist proves the miracle was never real, or the believer's faith survives only by ignoring what the data says. A science and faith thriller novel that lets both stand, unresolved and undiminished, in the same story is rarer than it should be.
Homecoming opens with a gravimeter anomaly that should not exist: a clean 40 Hz signal, pulsing every forty seconds, rising from a single acre of hillside north of Jerusalem. The data trail that follows does not lead a data scientist away from faith. It leads her, and two other people carrying very different kinds of belief, straight back to a 3,000-year-old site where something has been happening on a quiet schedule for longer than anyone has been measuring it.
Inside GEOMAPSE: The Data That Started It All
Then, at 11:47 p.m., the same structured pulse comes back for the fourth time that night. Forty hertz, in the low gamma range. Modulating every forty seconds, with a regularity too precise to be geological noise. Localised to less than an acre of hillside roughly twenty-four kilometres north of Jerusalem, the same coordinates, showing up in four separate datasets gathered by different instruments across different decades.
Rahul brings in Catalina Alba, whose discipline with strange data is exactly what the signal needs before it goes anywhere else, and Cole, a researcher who has spent twenty years quietly tracking persistent geomagnetic deviations that the standard models round off as noise. Satellite imagery pulls up an ancient dome structure and a solitary, centuries-old oak at the edge of the frame, and the signal's centre sits directly beneath the tree's canopy, not the ruin beside it. Within forty-eight hours, the three of them are airborne, flying a cover story into the region to see, in person, what the data has been trying to tell them.
For readers of science and religion fiction books who want the science taken seriously rather than treated as a rival to belief, this is the thread that carries that promise from the first chapter.
The Real Science Behind the Story
GEOMAPSE's core discipline is real, even though the specific anomaly it detects in Homecoming is fiction. Gravimetry, the science of measuring tiny variations in Earth's gravitational field, is used every day to infer what lies beneath the surface: buried structures, voids, changes in rock density. Pair it with geophysical anomaly detection and satellite gravity mapping, and you get exactly the kind of layered, multi-instrument evidence trail that convinces a careful scientist like Rahul that a signal is not measurement error.
The novel keeps an honest line between that real science and its fictional discovery. Nothing in gravimetry predicts a forty-second modulation rising from the roots of a single tree. That leap is the story's invention. But the instruments, the cross-checking discipline, and the reluctance to explain away inconvenient data are drawn directly from how working geophysicists actually operate, which is what gives the anomaly its weight before a single supernatural claim is made.
| Real-World Concept | What It Actually Is | How Homecoming Uses It |
|---|---|---|
| Gravimetry | The science of measuring tiny variations in Earth's gravitational field to detect what's beneath the surface. | The basis for the anomaly Rahul detects, grounded in a real discipline, not invented physics. |
| Geophysical anomaly detection | Identifying subsurface structures (voids, chambers, dense materials) from surface-level data. | Drives the modern-day thread that leads the story back to the ancient site. |
| Satellite gravity mapping | Using orbital instruments to map gravitational variation across large areas. | Referenced as part of the GEOMAPSE system's plausible technical backdrop. |
How Homecoming Compares to the Usual Science-vs-Faith Story
A faith-based thriller ebook Ireland readers can trust to hold both sides fairly is harder to find than the genre labels suggest. Most science thrillers resolve toward a rational, faith-neutral answer; most faith fiction resolves toward a spiritual one, with the science quietly set aside. Homecoming is built so that neither thread gets to win at the other's expense; the data and the belief are pointed at the same discovery, and both have to be reckoned with by the end.
| Aspect | Typical Science Thriller | Typical Faith-Based Fiction | Homecoming |
|---|---|---|---|
| Core tension | Human vs. unexplained data | Human vs. doubt or belief | Data and belief converge on the same discovery |
| Setting | Labs, research facilities | Churches, communities, personal struggle | A real geophysics lab and a 3,000-year-old sacred site |
| Protagonist's conflict | Proving the science is right | Reconciling faith with hardship | Proving the science AND reckoning with what it uncovers |
| Where it usually leaves the reader | Faith-neutral, purely rational resolution | Science-neutral, purely faith-based resolution | Both threads resolve together, neither dismissed |

Meet the Author Who Connected the Dots
Constance Mwayuli is an Ireland-based author, and Homecoming is her debut novel, published by Ireland Publishing House. The GEOMAPSE thread didn't come from nowhere; it grew out of a genuine interest in how real geophysical instruments detect what can't be seen from the surface, and what happens when careful, rigorous data collides with something the instruments were never built to explain.
That same instinct for research runs through the rest of the novel: an ancient hidden chamber researched with archaeological care, and a present-day Gaza thread written with a restraint that refuses to turn real suffering into backdrop. It's this grounding, across three very different disciplines, that lets Homecoming hold science and faith together without flattening either one.

More From the World of Homecoming
GEOMAPSE's signal isn't the only thread converging on that hillside. Three hundred metres downhill, a sealed chamber has been guarding a 4,000-year-old record of its own: a booby-trapped vault, a stone tablet carved with figures caught mid-lift above the ground, and a black-ops team racing to reach it before anyone else does.
If the data side of Homecoming pulled you in, the physical dig is where the story's other half plays out.
Is This Novel Right for You?
No one wants to spend a week with a book that leans too hard one way and leaves the other half of the premise as decoration. Homecoming is built for readers who want both taken seriously.
This is likely your next read if you are:
A hard-science thriller reader who wants more meaning underneath the plot mechanics, not just a bigger conspiracy
A reader of faith fiction who wants a stronger plot engine driving the story forward, not just internal reflection
Someone tired of being asked to pick a side before the first chapter is even over
A reader who wants a multi-thread structure, ancient origin story, modern science, and present-day human stakes, that actually converges by the end
What Readers Are Saying
"I kept waiting for the science to debunk the faith, or the faith to explain away the science. It never does. That's what makes this one stick with you."
"The Gaza thread alone is worth the book. I wasn't expecting a thriller about an ancient signal to be the thing that made me cry."
"As someone who works in data, I appreciated that the technical side wasn't dumbed down or played for spectacle. It felt like real research."
"I've read a lot of faith fiction and a lot of thrillers. I haven't read one that trusted me to hold both at once until this."
"Slow-burn in the best way. Four storylines, four thousand years apart, and they all land in the same place at dawn. I didn't see it coming."
Frequently Asked Questions
What is a science and faith thriller novel?
A science and faith thriller novel is a story that treats scientific inquiry and religious belief as threads pointing toward the same mystery, rather than opposing forces. Homecoming builds its plot around a real geophysical discovery and an ancient, sacred site that both explain and resist full explanation.
Is Homecoming based on real scientific research?
Yes, in its foundations. Gravimetry and geophysical anomaly detection are established, real-world fields used to find what lies beneath the earth's surface. The specific 40 Hz signal and its source are fictional, but the instruments and methods that detect it are grounded in genuine science.
Where can I buy this faith-based thriller ebook in Ireland?
Homecoming is available now as an ebook for Kindle and other major e-readers, with instant download at checkout. Use the buy link above to get your copy today, wherever in Ireland you're reading from.
Does Homecoming favor science over faith, or treat them equally?
Neither side is asked to yield to the other. The novel's structure keeps a data scientist, a priest, and a family of faith on separate but converging paths, and the ending resolves both threads together rather than letting one quietly explain away the other.
What is GEOMAPSE, and is it a real technology?
GEOMAPSE is the fictional data-fusion system built by the character Rahul at NASA Ames, combining real categories of geophysical data, satellite readings, ground surveys, and magnetometer data, into one map. The system itself is invented for the story; the underlying data types it draws on are real.
Is Homecoming suitable for readers who aren't religious?
Yes. The science thread is written with enough rigor to satisfy a purely secular reader, and the faith elements are handled as lived experience within the story rather than doctrine aimed at the reader. No prior religious knowledge is needed to follow or enjoy the plot.
