Charlie Green is the epitome of kindness, bold, good-natured and always seeks to find truth and put right wrongs with a cheeky grin. But Charlie is no ordinary boy, he has a secret: a magical plane that can take him anywhere including back in time! In Martyn Blunden's latest adventure, Charlie must travel back to the sixth century to save Camelot and the Knights of the Round Table from self-destruction. When an old man in a museum reveals some long lost parchments which contain a confession by Merlin, the great wizard and advisor to King Arthur, and a revelation of treachery within Camelot, Charlie knows that history will have to be rewritten. He must travel back in time to warn King Arthur and to stop the millennia old lies that Sir Lancelot betrayed his beloved king. Charlie knows little about the century he is visiting and upon arrival finds great difficulty in persuading its inhabitants to listen to him. The answer to his problems is locked away on the magical island of Avalon and is guarded by many, entrusted with total protection of its secrets. Let the adventure begin!
