Kate Maddox

Twenty years ago Kate Maddox was a volunteer at a research centre where scientists hunted for a cure for the common cold virus. That summer Kate fell in love with a handsome young doctor, Stephen, but her stay ended in his tragic death, and Kate fled to a new life in the United States. Now Kate is back in England and on the run with her young son, this time from her vile husband. But a chance encounter sets her on a terrifying path of discovery. What really happened at the Cold Research Unit two decades ago?

Two years on from uncovering a terrifying conspiracy of rogue scientists, all Kate Maddox wants is to lead a normal life with her partner, Paul, and son, Jack. But then a face from the past turns up, bringing chilling news. A devastating new strain of the virus that killed Kate's parents is loose in LA - and when a bomb rips through a hotel, killing many top scientists, it becomes clear someone will do anything to stop a cure being found.
