A lost treasure.
A relentless enemy.

In a world of secrets,
will she be his greatest ally—or his most dangerous foe?

In Nazi-occupied France, a soldier’s oath doesn’t end on the battlefield.

Haunted by the ghosts of his fallen comrades, Nicolas Durand thought he’d found a safer way to serve: protecting priceless artifacts from the Reich as a covert operative for the French Resistance. But when a mysterious professor and an alluring woman draw him into a race against the Gestapo, Nicolas realizes he’s hunting something far more dangerous than art.

From the peaceful coastlines of southern France to the shadowy depths of the Parisian catacombs, When Atlantis Calls is a spellbinding tale of romance, redemption, and courage in the darkest of times.

Austrian novelist Tina Hagmann masterfully weaves romance and historical thriller into an unforgettable adventure that will keep you turning pages long into the night.

Join the journey and discover
why some treasures are worth dying for.
