What begins as a relaxing vacation turns into a time-traveling
adventure, where Geronimo Stilton must travel to Khanbalik, or "The City
of Khan" (modern day Beijing) in 13th Century China where he encounters
Kublai Khan and Marco Polo. This time, Geronimo and friends must stop
the Pirate Cats from corrupting Marco Polo's famous book "The Travels of
Marco Polo," and changing history forever!
