It seems if he is to save Sue and his girlfriend Emma he will have to fly. But where? More
Sole survivor, Sam Kahu's secret memories of training and travel surprise detective Sue Williams in more ways than one. Not only are they darker, deeper, and more disquietening than those of most troubled teens she deals with; they are also more dangerous - especially when they come to her door.
But Sue discovers that if Sam's enemies take her to the limits of her comfort zone, his friends are even worse. They leave her notions of personal security sprawled in the dust, light-years behind.
Slowly Sue begins to realise that it is only Sam and his friends who stand between Earth's population and a secret society intent on shaping humankind's future with genocidal bioweapons. And worse, the fire at the mansion which brought Sam into her life, meant the secret society was on the threshold of winning.
