Without Warning is an alternate history novel written by the Australian author John Birmingham. It was released in Australia in September 2008 and in the United States and the United Kingdom in February 2009. It is the first book in a new stand-alone universe. The novels After America and Angels of Vengeance continue the story.
In Kuwait, American forces are locked and loaded for the invasion of Iraq. In Paris, a covert agent is close to cracking a terrorist cell. And just north of the equator, a sailboat manned by a drug runner and a pirate is witness to the unspeakable. In one instant, all around the world, everything will change.
A wave of inexplicable energy slams into the continental United States. America as we know it vanishes. From a Texas lawyer who happens to be in the right place at the right time to an engineer in Seattle who becomes his city’s only hope, from a combat journalist trapped in the Middle East to a drug runner off the Mexican coast, Without Warning tells a fast, furious story of survival, violence, and a new, soul-shattering reality.
