A killer is loose in paradise! Who will be the next victim? Paul Mila returns with familiar and new characters in the fifth book of his dive adventure/thriller series. Scuba diver and art gallery owner Dayle Standish struggles to save her marriage as she searches for a priceless artifact dating back to Christopher Columbus. But Dayle's path through the land of the ancient Mayans intersects with a vicious killer in Cozumel, Mexico, putting herself and her friends, Terry and Joe Manetta, in danger. The story will appeal to divers and non-divers alike, and diving readers will recognize dive sites located in Roatan and Cozumel. The unique story line takes readers inside cenotes (pronounced SAY-NO-TAYS), the underwater caves that riddle the Yucatan, and which supplied the ancient Mayans with much of their fresh water. "Paul Mila returns with familiar characters in this riveting suspense/thriller. Once you start reading, you won't be able to put this action-packed page turner down." Mike Monahan, author of The Treasure of Hart Island and Barracuda. "Paul Mila has created a fast-paced thriller that finds its 'Maltese Falcon' hundreds of years older and in an underwater Mayan shrine. Grab your air tank -- definitely worth the dive!" Thomas Hoover, author of Caribbee.
