A terrible virus has wiped out much of the human population and Scotland is now a wasteland. Toby and his family are being held hostage on the island of Orkney by a terrifying militia group called The Corporation. Toby knows he must escape and find his way to Edinburgh, if he is ever to bring about an end to the carnage that the Red Fever has caused. Arriving in Edinburgh with his friend Tash and her wolf-dog Snowy, things are even worse than he feared: the city is deserted, and overrun with rats. All they have is a name — but can they find the one person who could help them save not only their friends and family, but the whole world? The third book in the gripping Red Fever trilogy is packed with adventure, excitement, surprises and danger at every turn.
