It’s 1990, and Brigadier Lethbridge-Stewart is struggling to find his place in a new decade and among his newly discovered family. Sinister new students are undermining him every day, while Brendon School seems to be falling apart around him.

Increasingly isolated from his job and his life, the Brigadier must track down the source of the spreading decay. Why are piles of rubble shaped like people appearing everywhere, and can they really be moving of their own accord? What is really happening at the secret raves in the woods, and how are they affecting the youth of the school?

The Hiraeth have returned, desperate for new bodies. They will do anything and promise anything in return for life. And now they’ve found the perfect army to manipulate and a promise that no one can resist.

As the world prepares for the dawn of a new era in mobile communications, another old enemy is waiting in the wings. The Brigadier must seek help from his own past, and battle demons within, to fight for the future of the human race.
