It uses your DNA against you.

It knows no mercy, and feels no pain.

As the old world burns, only one truth remains.

IT. FOUND. US.

It's the middle of the night. The city's in total blackout. As the last cell tower fails, Lucy gets a desperate warning.

"Worse is coming."

In less than 24 hours, mass looting will begin. Panic will quickly follow. Then violence. Technology has failed across the globe, and a disastrous chain reaction has begun. But as the people of San Francisco sleep, they have no idea what's about to happen. Lucy must seize her chance to get ahead.

As the last bytes of data vanish into the ether, the old world will be lost. In its wake, billions of citizens will be stranded in defunct cities, unable to communicate, or coordinate. For the first time in millennia, our species will be truly vulnerable.

That's when the pandemic hits.
