The world is crumbling, everyone knows the story, everyone's seen it happen a billion times on TV - But nothing prepares them for the real thing. Can you really shoot someone who you've known for your entire life if your life depends on it? Can you mercilessly ignore the cries of the weak, frail and old; do you have the heart to kill a person who you know is trouble, who threatens your survival? This is the lowest bar to survive in a new Earth and one girl hangs on by the skin of her teeth. In a dog-eat-dog world, it is not an easy task for a child to survive. But Sen manages, she takes no risks and hides at the sight of other humans. No one can be trusted. But peace cannot last forever and it will not. News of Alaska opening its borders sweeps throughout a desolate America and millions begin a months-long trip to across the continent to what seems to be a new hope. Sen can't possibly hide forever and she knows this might be her one true chance at regaining a safe living, but she also knows the first rule of the new Earth. No one can be trusted.
