It is the year 490. You have travelled back to Britain during the Dark Ages. You are escaping from enemy Picts when you become lost in a snowstorm. You spot red eyes glowing nearby -- and suddenly a savage wolf leaps at you out of the wilderness! Should you fight the ferocious beast or try to run for your life in the blinding swirls of snow? Your decision can lead you to safety or leave you stranded in time! Are you ready to face the danger? The Time Machine series challenges young readers to use their imagination and decision-making skills to write their own story. Options in the text allow readers to choose any path they like within the plot. Readers must draw on background information about the period to make the right choices. This makes the series a great educational device for youngsters to learn about history and all the different cultures, events, and periods that shaped it.
