The 39 Clues
A pair of tungsten swords from Vienna leads Amy, Dan, and Nellie to Japan for a clue related to Japanese warrior Toyotomi Hideyoshi. Teaming up with Alistair Oh and the Kabras, the three follow a trail of clues to Korea, where they stay at Alistair's house. The Kabras have an interesting coin. A book in Alistair's secret library leads them to a mountain called Pukhansan. The group finds an entrance to a cave that uses the coin and hides Hideyoshi's treasure, and the third clue, gold. Dan decodes an anagram and tricks the Kabras, who escape and seal everyone else in the cave. Alistair is presumed to be dead but faked. After escaping, Dan, Amy, and Nellie head for Egypt, as hinted in the anagram.
