Some things are darker than eternal night...
Morgan Bale's wounds have healed but the scars are deeper than ever. Haunted by visions of a plane crash, he hides from the war as surely as he hides from the sun, always wondering which of those lethal dangers will get him first.
But within the endless night of the High North, a greater threat is growing. Abandoned mineshafts echo with the sound of unholy experiments. The Nazis have dragged what Soviet scientists began to a lower level of Hell. Morgan's fellow Mullo, a team of K Department commandos, even the enigmatic Lida - all are waiting for him to lead their mission to destroy the nightmare.
Knowing the nightmare is waiting for them.
Torn between his duty to Britain and his responsibility for his own people, Morgan can no longer stand to one side. Because if the evil beneath the ice ever reaches the surface, K Department and the Mullo will fall together.
And the world will follow.
