The Swiss Enigma: SECRETS OF THE ALPS

High in the Swiss Alps, where silence protects secrets and mountains guard what the world was never meant to see, the truth finally turns dangerous.

After uncovering ancient seals in the Holy Land, sisters Chloe and Lily Hastings follow the trail of The Society into Switzerland, where hidden vaults, coded ledgers, and impenetrable banking systems conceal a truth far more powerful than they imagined.

This time, the enemy doesn’t hide underground.

It hides in plain sight.

Beneath pristine cities and snowbound peaks lies a financial network built on secrecy, one that has quietly shaped wars, erased fortunes, and rewritten history for centuries. As the Sisterhood Sleuths unravel encrypted accounts, alpine codes, and long-buried records, they discover that money is the final weapon, and knowledge the ultimate currency.

But secrets of this magnitude demand loyalty.

When trust fractures and betrayal strikes from within, Chloe and Lily are forced to confront the most dangerous truth yet: not everyone fighting beside them is who they claim to be.

With danger closing in through frozen tunnels, abandoned strongholds, and shadowed mountain passes, the sisters must decide how far they’re willing to go to expose a system designed to never be seen.

Because once financial power is revealed, there is no going back.

Tense, intelligent, and breathtaking in scope, The Swiss Enigma raises the stakes of the Sisterhood Sleuths series, blending real-world banking history, modern espionage, and emotional suspense into a gripping international thriller.

This series unfolds in order.

For the full impact of the mystery, readers are encouraged to begin with Book 1: The Obsidian Eye, where the first clues are uncovered.

Perfect for fans of National Treasure, Da Vinci Code–style mysteries, and YA thrillers with global intrigue and emotional depth.
