Meltdown: Terror at the Top of the World tells the story of seven American hikers who travelled into Canada's Arctic tundra – polar bear country – and nearly didn’t make it back alive. But Meltdown is more than just another wilderness adventure story because its backdrop is the melting Arctic, where the battle between man, beast and nature in a warming world is most visible and visceral. The book is based on interviews with all seven hikers as well as many of the world’s experts on polar bears and sea ice. It also includes first-hand reporting from the site where the hikers pitched their tents one fateful night next to a breathtaking fjord.
