`The seconds extend, filled with horror. I don't have an answer. I don't know what my father did to us. He left only one word: Kingfisher. I thought I'd figured it out, but I was wrong. Everything is too late, and now I'm going to die.'
Sixteen-year-old twins Dominic and Charley are on the run. Their father, a respected scientist with LifeStar Corporation, has been arrested and accused of treason.
The war between the security services and eco-terrorists is getting closer - both MI5 and the Disciples are after them.
Seeking refuge, they head to the Highlands with their cousin Flint. But Dominic is convinced their survival depends on deciphering his father's code word: KINGFISHER.
