Prophecy. Power. Payback. Celtic Omen ignites the final showdown that began in Tuscan Hoax and Louvre Escape . Some call it the Bethlehem Star. Others say it fulfills a darker, older prophecy. Astronomers insist it’s a once-in-a-lifetime event. But does it bring salvation—or destruction? Darwin Lacroix, the Vatican's head of archaeological threats, is drawn into a storm of myth and danger in the explosive conclusion of this gripping trilogy. When a newly discovered comet appears on a collision course with Earth, panic spreads. Darwin uncovers evidence that Copernicus saw it too—and left behind a warning, hidden in a star map protected by a secret order: the Aedui Society. Until the Nazis stole it. Their experiment— Weltennaht , “the World Seam”—sought to control Earth’s magnetic field using ancient druidic alignments. And it didn't die with the Reich. The Americans quietly absorbed it in Operation Paperclip. Now, amid the celestial chaos, others see opportunity. Jasmin Kahn, newly paroled and more dangerous than ever, leads a global antiquities syndicate—and plans the greatest museum heist in history. As the comet sparks a geomagnetic storm, Darwin faces a cosmic reckoning while his partner Eyrún races to stop Jasmin. With ex-Army intelligence officer Zac Johnson at their side, the fnal battle begins Because when the stars align, the world will either be reborn—or torn apart. And Jasmin Kahn? She is the omen.
