The grown-ups are all gone and children rule the new world. Harry lives in a strange utopia: resources are plentiful, the climate has stabilised, there is peace. His village is watched over by an invisible force that keeps them all from danger - but is it protecting them, or holding them back? Join Harry and his friends as they embark on a journey to unravel the mystery of what happened to the old world, and what is wrong with the new. They might not like what they discover. From the writer of the Watty-winning A Day of Faces and The Mechanical Crown.
