The world is in chaos: war, plague, global ecological collapse. Parents everywhere seek sanctuary for their precious children, the future of mankind. For those who are rich and powerful enough, safety can be found for a price - at Clothos Academy. Run by a mysterious man known only as Sarge, set in a former monastery atop a sheer cliff on a tiny island somewhere in the Mediterranean, Clothos will admit only one hundred children before it is sealed off - perhaps permanently - from the terrors outside.
But all is not as it seems. The students are hardly the best and the brightest: so-called starlets best known for their empty heads and eating disorders; troublemakers one step away from incarceration; junior royals too embarrassing to be let out in public. The staff isn't much better, from the alcoholic doctor to the last resident of the monastery, an ancient monk with secrets of his own.
And the dangers from which these castaways are being protected? They're stored on DVDs, ready to be trotted out whenever Sarge needs to terrify his little flock. And yet ... the dangers are real, as two boys discover when they hack into the Academy's computer network and connect, for a brief but disastrous moment, to the outside world. But the computer virus isn't the worst invader ... a stranger has entered the Academy. And he has brought Death.
