This story begins with a young cousin of Indiana Jones traveling with him to Venice for a quiet vacation. They meet up with Giacomo Andrini, an acquaintance of Jones and owner of an antique shop, who claims to have found a diary of Marco Polo's. The diary speaks of an enormous treasure hidden in Mongolia, which both men are interested in.

At this point, the story begins to offer the reader decision points, sending them to various pages for alternate story lines resulting in multiple endings. Its kind of fun, except that on page 33, it tells the reader who makes one choice to go to page 111; the plot on that page doesn't make any sense with what has gone before. I think it is supposed to send the reader to page 34. ( )
