The sins of the past come back to haunt Doc Ford and his old friend Tomlinson in this thrilling new novel from New York Times-bestselling author Randy Wayne White. Marine biologist and former government agent Doc Ford is sure he´s beyond the point of being surprised by his longtime pal Tomlinson´s madcap tales of his misspent youth. But he´s stunned anew when avowed bachelor Tomlinson reveals that as a younger man strapped for cash, he´d unwittingly fathered multiple children via for-profit sperm bank donations. Thanks to genealogy websites, Tomlinson´s now-grown offspring have tracked him down, seeking answers about their roots. . . but Doc quickly grows suspicious that one of them might be planning something far more nefarious than a family reunion. With recent history on his mind, Doc is unsurprised when his own dicey past is called into question. Months ago, he´d quietly liberated a cache of precious Spanish coins from a felonious treasure hunter, and now a number of unsavory individuals, including a disgraced IRS investigator and a corrupt Bahamian customs agent, are after their cut. Caught between watching his own back and Tomlinson´s, Doc has no choice but to get creative--before rash past decisions escalate to deadly present-day dangers.
