The Radleys 

FAMILIES. SOMETIMES THEY»RE A BLOODY NIGHTMARE . . . Life with the Radleys: Radio 4, dinner parties with the Bishopthorpe neighbours and self-denial. Loads of self-denial. But all hell is about to break loose. When teenage daughter Clara gets attacked on the way home from a party, she and her brother Rowan finally discover why they can»t sleep, can»t eat a Thai salad without fear of asphyxiation and can»t go outside unless they»re smothered in Factor 50.With a visit from their lethally louche Uncle Will and an increasingly suspicious police force, life in Bishopthorpe is about to change. Drastically.
