Clear Fountains - the largest shopping centre in southern Britain. Hundreds of shops, restaurants and leisure facilities designed to entertain and delight the thousands of shoppers who visit on a daily basis. When Edward turns up with Wanda and her daughter Sarah, they find the car park full to bursting - but not a single person to be seen anywhere. Clear Fountains - the bustling, crowded retail paradise - has fallen empty and silent. Almost. For within its walls, a desperate battle for survival is taking place. The Skree have come, and the hunt is on.
