Lt. Colonel Dana Wright has barely started as deputy commander of Thule Air Force Base in remote northern Greenland when a fireball in the sky changes everything. Fighting massive fires kicked off by the flaming meteorites, losing communications with the U.S. and having civilian contractors abandon the base are just the beginning of her challenges. Soon Dana and the embattled Air Force personnel are facing off against the belligerent commander of nearby Camp Amarok, a mysterious Arctic facility claiming to conduct ice cap research but whose true mission has remained a closely guarded secret. And Dana’s worries don’t stop there, her photographer husband, on a Greenland photo shoot accompanied by their 12-year-old daughter, has disappeared and Dana doesn’t have the people, helicopters or time to search for them. When the Amarok commander demands that Dana turn over the base’s only C-130 to fly his team out, it sets off a confrontation that reveals what’s behind Amarok’s closed doors and pushes Dana to the limit.
