A mysterious force captures Earth and gives humanity thirty days to move to Antarctica, where they will be allowed to exist and survive in the planet's most extreme environment.

Bernadette is a frightfully intelligent wife and mother whose intense allergy to Seattle specifically, and to people in general, has driven her to hire a virtual assistant in India to execute even her most basic tasks. Then her daughter, Bee, insists on a family trip to Antarctica as her reward for getting perfect grades in middle school, and Bernadette is faced with the daunting prospect of actual human interaction. And then Bernadette disappears....

Following clues provided by the secretive Reddimus Society, the four Alden siblings travel to a dingo sanctuary in Australia and to Shakleton's hut in Antarctica to deliver the fifth and sixth artifacts, and then they work to unmask the traitor traveling with them.

Once again the mysterious box takes the golden retriever Ranger back in time, and he finds himself on Robert Falcon Scott's ship, the Terra Nova, headed for Antarctica, where his mission is to save Jack Nin, a Chinese-Maori stowaway from New Zealand, from the blizzards, unstable ice, and the other hazards that lie ahead for the doomed expedition.
