Faced with an epidemic of 13 million new cases of cancer, the World Health Organisation has offered a reward of US$7.5bn for irrefutable proof of a scientific cure. Leading American oncologist Dr Hannah Siekierkowski discovers a secret buried in a London research laboratory that will change medical science and raise new questions about the cause of the disease. It could save the lives of millions of innocent people. But she is not the first to make the discovery. Now Hannah's own life could be at stake as she uncovers acts of cruelty perpetrated in the name of medical science and faces a life-threatening dilemma within her own family.
