A travel feature turns into a deadly investigation for Kat Lawson when she discovers a missing passenger, presumed overboard, may have been used as a mule to smuggle ancient artifacts aboard Athena, a luxury cruise ship designed for retired seniors at sea. Kat Lawson has got a plumb assignment, or so she thinks. Travel International has rewarded her with a vacation cruise along the Amalfi Coast to report on a new floating senior retirement center. After working undercover as a travel reporter for the FBI and barely escaping her last assignment with her life, Kat's job is to relax, take notes, shoot pictures, and report back on an extravagant cruise from Naples to Positano. What could go wrong? But once aboard, Kat quickly learns it's not all smooth sailing. Kat finds a handbag for Dede Drummerhausen, the woman who owns the suite where Kat is staying, and hidden inside is a gold coin. Rumor abound. Passengers and some of their possessions have gone missing. The residents are restless, and some on board are suspicious of a travel reporter who might uncover their secret mission. When Athena's captain discovers Kat snooping below deck, she soon realizes, like the antiquities hidden onboard, that she's been kidnapped and that her job and her life are in danger.
