Escaping Los Angeles for a weekend can be a chore. Escaping Los Angeles during an apocalypse? That's next to impossible. When civilization has turned on itself, when your friends and family aren't answering the phone, who do you have left to depend on? What if you fear depending on others? In a catastrophic event, survival depends on breaking habits.

Dragging along a police officer, a car thief, and a disabled military veteran can prove to be even more of a challenge than someone like she could ever have imagined, but the challenges keep piling up. From a murder in a park to an attack in a hospital, the story keeps on rolling.

She's a determined, bullish, independent woman who's been on her own since childhood. She's seen the worst of humanity most of her life. Living through an apocalypse would be nothing new.
