A modern city can feed itself for nine days. No more. And when the panic starts...

In the pulse-pounding thriller Zero Day Code by best-selling author John Birmingham, civilization unravels at a keystroke. Chinese cyber strikes pierce the heart of the free world-no food, no water, no power. America starves, and darkness descends, igniting a global cataclysm.

From the chaos, a small band of survivors emerges. James O'Donnell, a shrewd farm boy turned market analyst, unearths the truth behind the digital Pearl Harbor. Michele Nguyen, enigmatic agent of the Deep State, carves a path out of a crippled capital. And Jodie Sarjanen, a fierce single mother, navigates the ruins of San Francisco.

As society reaches breaking point, unlikely heroes brave a treacherous world of newfound friends and ruthless enemies like Jonas Murdoch, a charismatic firebrand who leads the dangerous Legion of Freedom.

Not since Stephen King's monumental epic 'The Stand' has a novelist worked on such a grand scale, where the end of days is just the beginning-when every choice could be your last, and the battle for tomorrow is waged today.
