AD 78: It’s taken the Roman invaders over thirty years to reach the Lake District and the lands now known as Cumbria. Surrounded by high mountains, deep valleys, and a multitude of lakes, tarns and sheep, the Romans speculate on whether the inhabitants are an illiterate band of semi-neolithic individuals or an affluent tribe of significant status. Perhaps they will prove to be rich in gold, silver, and other treasures mined from the rocky environment where they live. Or do the locals survive on the edge of starvation existing on a daily diet of basic nourishment that is below normal living standards? Where is their army, the Romans ask? Will they run and hide in the caves with the first flight of an arrow? Are the natives naïve or cultured? Can they be trusted? How long will it take to destroy them?
Ed Carter, an ageing career astronaut, is put out to pasture and dubbed a failure. Retiring to a quiet pub in rural Cumbria, he spends his time studying the stars in between pulling pints of beer for his thirsty locals. Envious of modern day space exploration, Ed can only watch from afar as his colleagues strive to reach further into the unknown. Then, unexpectedly, everything goes wrong and Earth is plunged into an alarming series of natural, and unnatural, disasters. Only Ed seems to know the answer to the problem the world is facing, but no-one is listening to yesterday’s man. Eventually, Sam, an astrophysicist, teams up with him and, together, they realise why the Earth is in danger.
