The red night of bells heralds global catastrophe. Annihilation on a biblical scale. Seeing the morning is no blessing. The handful of scattered survivors are confronted by blood-red skies and an infestation of predatory horrors that never originated on earth. An occupying force intent on erasing the remnants of animal life from the planet. Across the deserted landscapes of England, bereft of infrastructure and society, the overlooked can either hide or try to outrun the infernal hunting terrors. Until a rumour emerges claiming that the sea may offer an escape. Ordinary, unexceptional, directionless Karl, is one of the few who made it through the first night. In the company of two orphans, he flees south. But only into horrifying revelations and greater peril, where a transformed world and expanding race of ravening creatures await. Driven to the end of the country and himself, he must overcome alien and human malevolence and act in ways that were unthinkable mere days before.
