Haley left Dublin for a six-week internship in Seattle.
Four years later and she's living in the ruins of Washington State after the world fell in a cascade of nuclear bombs, computer viruses and human plagues.
When she is accused of her friend's murder, she flees into the night, with one destination in mind. Home to Marley, the love she left behind.
To escape her pursuers, skip around the swathes of chemical and radioactive waste, avoid the Kings, a roaming gang of marauders, she will need to use every bit of engineering knowledge she has.
Can she make it across the continent and an uncrossable ocean to finally get home?
Does home still exist, or did it perish in the Fall?
