Miyamoto Musashi was a well-known samurai during the 17th century. Your mission is to travel back in time to feudal Japan, learn the samurai customs, and find a way to bring back a sword Musashi has made famous. But you have to be careful; danger lurks everywhere, and you never know which samurai is after you! 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. Michael Reaves has written several books in the Time Machine series.
