The new white-knuckled thriller in the NUMA series from the No. 1 Sunday Times bestselling Grand Master of Adventure, Clive Cussler

When a NATO super-weapon is successfully tested at the North Pole, the aircraft carrying it suddenly vanishes off the radar, the crew are found murdered at their stations, and the weapon – capable of triggering global catastrophe – disappears into the Arctic mists.

NUMA’s Kurt Austin and Joe Zavala are pulled into a race against time to lead the search.

Rival Russian and Chinese powers are closing in, but as Kurt and his team race to reach the wreck first, a darker mystery emerges: the world’s great powers are all being carefully manipulated by one vengeful man with a deadly plan . . .
