It is 2375 and an ice age has descended on the Earth caused by climate change, known as The Big Change. Humans are few and close to extinction because of wars, famine and plagues created by virus nukes. Humanity's survival rests on the untested shoulders of three IMPs-Improved Model Persons-and a God-like ursine Caretaker who seek the fabled Svalbard Vault above the Arctic Circle. Here on the lost island of Spitzbergen an unknown treasure promises salvation or destruction to whoever finds it. Maris-12 ... Travik Svalbard ... Freya Henriksdottir ... and Huldra face an uncertain future in this strange land. They are Earth's last chance. But can they save the planet from the forces vowing to wipe humanity out of existence.
