Katie Douglas and Casey Malone, having survived revenge attacks from the Mafia and a scheming financier, are rewarded for thwarting plots aimed at guests of the famed Tawnee Mountain Resort. Billionaire owner Raymond Elliot has sent them on an all-expense-paid, month-long vacation to his private-island retreat in the Bahamas. But the couple, who are just beginning to enjoy their budding romance, finds it hard to relax in the tropical paradise when bodies keep washing up on the shore. Even more perplexing, the islanders won't talk about the strange goings-on that Katie and Casey encounter.
When they discover that the supervisor of the work crew assigned to build a private airstrip on the island has secret activities that he is willing to do anything to hide, they find themselves targets once more. They seek to solve the mysterious deaths and get to the bottom of who Jake Peters really is and why this beautiful piece of heaven has become an Isle of Deceit.
