Jason MacKenzie is a jaded journo for the New York Times who's tired of riding his desk and longs for adventure.
When his best friend and one-time art partner is murdered by a ruthless assassin on the hunt for an otherworldly bracelet that defies scientific scrutiny, he joins forces with the beautiful and enigmatic two-hundred-year-old witch, Eva, to search for both treasure and truth.
With this, he becomes the unlikely hero in a quest that takes him across Europe and up into the icy reaches of Canada, weaving back and forth between the present day and an ancient, fantastical past where celestial beings and giants roamed the earth.
Along the way he discovers an obscure connection between the Nazis, the occult and the Spanish Inquisition, meets an ancient Indian tribe tasked with safeguarding the future of the planet and encounters a diary, written by the painter, Goya, more than two hundred years ago, which tells of a secret, that if made public, would shake the very foundations of what we know of what it is to be human.
