Sail ahoy! Travel back to the 17th century and become a swashbuckling pirate! Your mission is to find the wreck of the richest silver ship ever to sink in the Caribbean Sea, and bring back some of the treasure. 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. James Gasperini has written several books in the Time Machine series.
