Upon arriving in Ilulissat, Greenland, Gannon and Wyatt prepare for the adventure of a lifetime--a dogsled expedition in the Arctic! But before the explorers even crack a whip, they receive a desperate mayday call from an Inuit family that is stranded in the far north. Suddenly, Gannon and Wyatt's expedition to study climate change and Greenlandic culture turns into something far more dangerous--a mission to save lives. As they rush north to rescue the family, led by Inuit guides, the brothers must steer clear of deadly hidden crevasses, hungry polar bears, and bitter cold as they race into an Arctic super-storm, putting even more lives in jeopardy--their own.
