YA. Science fiction. When the thick fog of the Veil descends for the second time, Dan and Ursula expect to return to present-day Britain. Instead, the treacherous mist transports them to an ancient world very like the one they have just escaped. But the battle they fought in only hours before is distant history to those around them and their deeds on the battlefield are legend. Dan and Ursula have travelled forwards through time, but how far? What has happened to their old allies and enemies? To find a way back, they have to piece the clues together and use all their skills of survival - as it seems they were not the only ones to step through the mist.
