Rewritten: The Travels of Marco Polo - Time Force, #3

Time is broken - again.  Yesterday, in the 12th century, Carly, Theo and Will, together with Iggy (Time Force Agent Ignatius P. Torres), made sure Temujin would make the Silk Road safe. And Marco Polo did use it to make his 24 year journey to China. However, he still hasn't told anyone about his trip.  In the 14th century, European explorers, traders, and everyday people learned about the wonders of China, its science and luxuries, by reading The Travels of Marco Polo.
But in this timeline, he never wrote the book. Can the trio help Marco Polo tell his story before all the European traders and explorers decide to stay home without fireworks, coal or paper money?  Join the trio as they race against the clock in their third of many adventures, repairing mysterious breaks in the timeline that could change our history forever.
