Twenty-five years into the future, no humans are allowed in the Wildlands - a vast area in Britain where wolves, lynx and bison roam free. The only exception is a high-speed train line between London and Glasgow that crosses right through the heart of the project.
Thirteen-year-old Astrid and her little sister, Indie, are onboard when their train slows to a brief, unexpected stop ... and they find themselves accidentally left behind.
Stranded in this place of astonishing natural wonders and terrible dangers, they have only a rucksack, a phone without signal - and each other. As every wrong turn takes them deeper into the Wildlands, do they have the ingenuity and determination to survive?
