So much had happened in the eighteen months since Jack and Agnetha's almost life-ending trials and tribulations at the hands of the Lithuanian Mafia and the Order of the Teutonic Knights in Vilnius.

A new life, new careers, a honeymoon in the Maldives... until the Code Red.

Their biggest challenge as JADE. Jack, Agnetha and Danny's newly formed Private Investigation corporation.

The Code Red would lead them into more intrigue and danger than they could have imagined possible.

A pursuit through the middle ages as Vikings plundered the north Atlantic.

A resolute young girl of Viking nobility, Audr the Deep-minded, standing fast against her father and his murderous warmongering.

She would expand her regime from the Orkney and Faeroe Islands to Iceland, producing a bloodline of aristocracy that would stand the test of time for over a millennium. A bloodline that would see Jack's team and his ex-SVR comrades from Vilnius stretched to the absolute limit.

Audr amassed what would equate to billions of dollars in priceless treasure troves over many years only to secrete them so well that they lay there forgotten for a thousand years.

But now, with the continuing greed of the Order, joining forces with Iceland's most notorious cyber criminals, will stop at nothing to recover the dormant cache.

Kidnapping of innocent children, a haunting memory from Vilnius.

A matriarch held to ransom, her twin children the bait.

The threat of death and destruction to all of Iceland.

Jack, Agnetha and Danny have to solve the puzzle of Audr the Deep-minded before the Order does. A problem that is made more complex by the need to unravel the secrets of the Sagas of Iceland, the magic of the northern grimoires and the advent of the Lutherans into Iceland.

Else two innocent children perish, and Iceland is subjected to the most significant act of genocide since World War Two.

Their chase through the landscape of the northwest Fjord country, western Iceland and the Laxa River valley provides a magnificent backdrop to Jack Carpenter's second chilling adventure.
