Summer 1930, Svalbard, Norway. A walrus-hunting boat sets sail for White Island, one of the last lands before the North Pole. The melting ice has revealed terrain that is usually inaccessible. As they move across the island, the men discover bodies and the remains of a makeshift camp. It is the solution to a mystery that has hung in the air for 33 years: the disappearance in July 1897 of Salomon August Andrée, Knut Frænkel, and Nils Strindberg as they tried to reach the North Pole in a hydrogen balloon. Among the remains, some rolls of negatives are found and one hundred images are retrieved. Based on these lunar-like black-and-white photographs and the expedition logbooks, Hélène Gaudy retraces and reimagines this great adventure that was blown off course, weaving in the painfully beautiful love affair of Nils and Anna. From the conquest of the skies to the exploration of the Poles, this haunting, award-winning novel, set in the ethereal landscape of the Arctic, reflects on the human need to discover, describe, conquer, and ultimately shrink the world.
