At the Point of Death Can the flap of a butterfly's wings in Brazil end up as a tornado in Texas? Chaos theory says yes it can. It says that dynamic systems are sensitive to their initial conditions and the slightest differences can have huge and unpredictable outcomes. So to guard against chaos we have laws and systems, procedures and regulations. Except they don't always work. A microscopic fault in a jet engine that brings down an airliner. A piece of foam that destroys a space shuttle. A virus mutation that goes on to kill millions. In the end, everything is subject to the laws of nature, including the laws of human nature, and if chaos theory applies to human nature, it might not take much to shift a person from law abiding to law breaking. In 2020, a terrorist organisation sets out to do just that. Create chaos. To bring society to that point where law and order breaks down. Across the world, wave after wave of atrocities begin to tip the balance. But what is the ultimate goal of the terrorists? In a hectic and sometimes chaotic journey from an idyllic Greek island to the International Space Station, it is up to Jack and Helen Riley to find out and stop them.
