Into the Forest haunts with its larger vision of a world in collapse, made all the more affecting because we’re told so little about it. One day the power goes out—with a whimper, not a bang—and then it simply never comes back. With all forms of mass communication gone besides rumour and Chinese whispers, humans are left very much in the dark. “That’s truthful to me,” Rozema remarks. “The absence of knowing is what’s going to be difficult for lots of people. I would find that just terrifying.”
Set in the near-future, Into the Forest is a powerfully imagined novel that focuses on the relationship between two teenage sisters living alone in their Northern California forest home.
Over 30 miles from the nearest town, and several miles away from their nearest neighbor, Nell and Eva struggle to survive as society begins to decay and collapse around them. No single event precedes society’s fall. There is talk of a war overseas and upheaval in Congress, but it still comes as a shock when the electricity runs out and gas is nowhere to be found. The sisters consume the resources left in the house, waiting for the power to return. Their arrival into adulthood, however, forces them to reexamine their place in the world and their relationship to the land and each other.

Set in the near-future, Into the Forest is a powerfully imagined novel that focuses on the relationship between two teenage sisters living alone in their Northern California forest home.
Nell and Eva live alone in the forest. Recently orphaned and completely isolated, they struggle for normality in a post-holocaust world where electricity is a thing of the past and the outside world a distant memory. In one short year, thie normal teenage lives have been transformed as everything we consider necessary to civilization crumbles. Without petrol or electricity they are forced into seclusion, and adolescent dreams of ballet school and Harvard are displaced by the reality of learning to survive.
Nell and Eva wait for the power to come back and the world they understand to return, but as time goes on they are forced to realize that 'civilization' is perhaps nothing more than a temporary condition, a 'fugue state' the world has allowed us. At once a poignant and lyrical portrayal of the power of sisterly loyalty and a horrifying cautionary tale about the future of man and his place in the world, INTO THE FOREST is a deeply moving account of human nature and our fragile existence on earth.
