A medical emergency at the South Pole requires immediate evacuation. One problem—it's midwinter and the Pole Station remains cut off for another four months. No one has ever flown to the South Pole in winter.

Ted Donovan, the chief pilot of Bernard's Ice Air takes the mission. But if he's going to survive, he needs to take the very best.

Jessica Ryan joined Bernard's as an expert mechanic but always dreamed of flying. When Ted gives her a chance, she leaps in. But her heart never counted on what else she might be flying into.
