From international bestseller Thomas Olde Heuvelt comes Oracle, a supernatural thriller where an omen from our past threatens the return of ancient forces that will change the world forever.

On a foggy winter morning Luca Wolf and Emma Reich discover an eighteenth-century sailing ship stranded on a barren flower field, its name written on its side: Oracle.

Emma, unable to resist, enters the hatch on the tilted deck. The ship's bell begins to toll and no one sees her again.

Not much later, eleven people have disappeared, Luca and his mother have been absconded by a clandestine government agency which has questions, no answers, and are determined to uncover the ship's secrets before a media storm erupts.

But as they force Robert Grim, a retired specialist of the occult with a strange history and a healthy dislike of authority, to unravel the mystery, the Oracle is revealed to be a harbinger of an ancient doom awakened underneath the sea.

What follows is a maelstrom of international intrigue, history, young love, humanity's relationship with climate and disease, and pure terror as they come face to face with an open doorway to apocalypse.
