Ash is still falling from the sky two years after a series of globally
devastating volcanic eruptions. Sunlight is as scarce as food, and
cities are becoming increasingly violent as people loot and kill in
order to maintain their existence. Sixteen-year-old Miles Newell knows
that the only chance his family has of surviving is to escape from their
Minneapolis suburban home to their cabin in the woods, As the Newells
travel the highways on Miles' supreme invention, the Ali Princess,
they have high hopes for safety and peace. But as they venture deeper
into the wilderness, they begin to realize that it's not only city folk
who have changed for the worse.
