The Finger-eater (Sprinters)

Long ago, in the cold lands of the North, there lived a troll named Ulf, who had a very bad habit - he liked to eat fingers! Many many men, women and children had found their hands a finger short thanks to the razor-sharp teeth of the Finger-eater. And who knows how many more might have suffered the same fate if it hadn't been for the actions of a resolute girl called Gudrun! The author won "The Guardian" Fiction Award for "The Sheep-Pig" and was named Children's Author of the Year at the 1991 British Book Award. His other titles include "Farmer Bungle Forgets", "H. Prince", "The Whistling Piglet" and the "Sophie" series.
