The Vault (Tyler Locke, #2)

Military engineer Tyler Locke's commute on a Seattle ferry is plunged into terror when an anonymous caller claims that his father has been kidnapped and that a bomb on the boat's car deck is set to detonate in minutes. Disabling the device alongside classical language expert Stacy Benedict who received the same threat and whose sister has been taken they are forced by the criminal genius behind the setup to undertake a seemingly impossible mission: uncover the legendary lost riches of King Midas. Armed with an ancient manuscript, and with just five days to thwart a plot for unspeakable devastation, Tyler and Stacy sweep from Italy, Germany, and Greece to the streets of New York City in a blistering race to unravel a 2,000-year-old puzzle that has eluded mankind.
