Book excerpt: Take a journey to a vanished world with the ADVENTURES IN TIME series - stories so exciting you won't believe they're all true 'Thunder crashed across the sky. Fire-dragons soared through the heavens. And then, one fine June day, came the warriors from the north - the Vikings...' Prepare to meet the most terrifying raiders the world has ever known, as historian Dominic Sandbrook plunges us back into the thrilling drama of the Viking Age. We'll encounter gods and giants, axemen and shield-maidens, from the warlords rampaging through King Alfred's England to the sea-captains who first glimpsed the mountains of Iceland.

These stories are every bit as exciting as those of Harry Potter or Matilda Wormwood. The only difference is they actually happened...
