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.

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.
