The countdown has begun...
"This is the first of three warnings. If you do not heed these warnings and if Allah, the Most Kind, the Most Merciful wills it, we will be forced to implement the final solution."
From China's western-most province, near its border with Pakistan, comes this deadly ultimatum. In the White House Situation Room, the President and his team dismiss it as one of thousands of threats made against the US every week. Their concern about China is not terrorism, but the growing economic might of Beijing.
But CIA agent Curtis O'Connor isn't so sure. The man making the warning is Dr Khalid Kadeer, a brilliant Muslim microbiologist. As an expert on bioterrorism, O'Connor knows Kadeer isn't bluffing. He knows what a scientist with a cause and a lab can do.
So too does Kate Braithwaite. She works in a hot-zone laboratory, on the USA's own top secret biological weapons, genetically combining Ebola, Marbug and Smallpox to create a super virus. If the results of Kate's research fall into the wrong hands, billions of people will die. As Curtis O'Connor and Kate Braithwaite work to unravel the riddles of the Kadeer's warning and prevent a devastating attack on the world's greatest sporting event, they begin to uncover a threat more sinister than they had imagined - a threat from within, from a man whose lust for power drives him to orchestrate a plan that will devastate the human race. And the clock is ticking.
