A new and updated novelisation of the classic Hammer film written by one of Britain's best known horror authors

In a quiet field in Buckinghamshire, a huge crack has appeared in the earth's surface. And people are dying. Incinerated beyond recognition. At the same time, hospitals have noticed an increase in catastrophic deformities in foetuses, and cancer levels soaring.

Dr Adam Royston, a scientist working at the nearby military base, thinks he knows what it is; a creature as old as the earth that slumbers for centuries, then wakes to feed on the energy and radiation produced by humans. But if he's right, and they can't find a way to destroy the creature roaming the countryside, then it's not just Buckinghamshire that could be in danger, but the whole world.
