The world has gone dark. And now danger lurks in the shadows... After a massive EMP attack cripples the West Coast, civilization collapses overnight. Claire's only focus is finding her sister Lydia-before it's too late. With chaos erupting around every corner, Claire is forced to team up with the last person she ever expected: her ex-husband. But in a world without rules, trust is a luxury they can't afford. Meanwhile, miles away in the remote wilderness, Lydia awakens in the wreckage of a plane crash-alone, injured, and pregnant. But this isn't just any pregnancy. Lydia is carrying a child for one of the country's most powerful and ruthless families... and now they want her back. Alive is optional. Armed with nothing but the survival skills their father taught them, the sisters must navigate a landscape where the only thing more dangerous than nature is the people still left in it. Their goal: reach the family's old homestead and ride out whatever's coming. The road to each other is dangerous-but it's the only one worth taking.
