Every palace hides a dungeon. This one hides something worse.

When a fire ravages the east wing of a centuries-old royal estate, restoration crews discover something impossible: an elaborate mechanical door sealed behind a false wall, untouched since Victorian times.

Before experts can investigate, the entire site is suddenly placed under "emergency heritage protection" and sealed by royal decree. No explanation. No timeline. No access.

But someone on the inside smuggles out a single photograph: an ornate key mechanism with a familiar symbol—the same insignia found on the agency's most classified historical files.

The team has 72 hours to infiltrate one of the most heavily guarded estates in England before the evidence is entombed forever:

Inaya poses as an architectural historian specializing in royal properties, gaining access to the main house—where every room is monitored, every conversation recorded, and staff have served the Crown for generations.

Sania hacks the estate's supposedly standalone security system, only to discover it connects to military-grade surveillance networks protecting something far more valuable than antiques.

Adisa explores a network of forgotten servant tunnels beneath the grounds, following centuries-old maps that reveal the estate was built not to keep intruders out—but to keep something in.

As they navigate booby-trapped passages, decipher mechanized puzzles, and dodge both modern security and historical deathtraps, the women uncover the estate's true purpose: a testing ground for experimental weapons and intelligence techniques deployed throughout the colonies.

At the heart of the labyrinth lies a chamber containing artifacts that could rewrite the Empire's history—and destabilize the monarchy itself. But they're not the only ones racing to claim this explosive legacy.

A ruthless black-ops team with royal authorization has orders to eliminate all witnesses. The estate's caretakers harbor their own agenda generations in the making. And a familiar enemy has infiltrated the agency's communication channels, hearing every word the team speaks.

Some secrets were buried for a reason. Some labyrinths have no exit.

THE QUEEN'S LABYRINTH delivers breathless action and mind-bending puzzles in a high-stakes historical treasure hunt where the greatest danger lurks in the spaces between truth and legend. For fans of NATIONAL TREASURE, THE DA VINCI CODE, and TOMB RAIDER who crave intelligent heroines unlocking history's deadliest secrets.

The most dangerous trap isn't the one that kills you. It's the one that makes you question everything you thought was true.

One-click now to enter the labyrinth—before the walls close forever.

ABOUT THE SERIES

Uncover Imperial Secrets with Rose Sandy’s Daughters of Empire Series

Daughters of Empire is a high-energy, female-led action-adventure and espionage series by Rose Sandy for readers who love smart heroines, global stakes, and stories that aren’t afraid to dig into the shadow side of empire. Set in the aftermath of the British Empire, the series follows three extraordinary women — Sania, an Indian cyber-sleuth, Adisa, an African field operative, and Inaya, a Middle Eastern corporate-intel expert — recruited into a covert taskforce to expose the crimes, thefts, and cover-ups hidden in imperial archives.

As they chase looted artefacts, suppressed files, offshore fortunes, and powerful families desperate to stay untouchable, the women must confront not only today’s enemies, but the ghosts of colonialism itself. Each book is a globetrotting mission featuring secret auctions, vault break-ins, diplomatic cover, ancient codes, and dangerous men with old money and older grudges.

READ A SAMPLE

Meet the Author

Rose Sandy is an international thriller and adventure author who writes high-velocity stories about brilliant women taking on the world’s most powerful institutions. From secret archives and looted artefacts to covert taskforces and royal scandals, her books blend espionage, history, and heart. She’s especially interested in the legacies of empire — who controlled the narrative, who profited, and whose stories were erased — and she puts those questions in the hands of fearless female protagonists.

In the Daughters of Empire series, Rose brings together three women from across the former British Empire — a hacker, a spy, and a corporate infiltrator — and lets them do what history never allowed: expose the truth. Her fiction is fast-paced, globally set, and rooted in real-world global happenings, but always centred on sisterhood, justice, and women who refuse to be silenced.

When she’s not plotting international conspiracies on the page, Rose champions diverse storytelling, mentors authors, and builds publishing experiences through Silver Gravity Entertainment.
