A sinister spell had been cast... As a troubleshooter for Sunshine Tours, Marti Winston found her work sometimes routine and sometimes exciting. On her latest assignment in the Dominican Republic, it had taken on a whole new dimension. Peril. To her heart--and to her person. Her heart was threatened by Antonio Andreas, magnetic owner of a resort plagued with problems that had little to do with bad luck or management. Someone, it seemed, was out to force Antonio into bankruptcy, and Marti found herself embroiled in finding the saboteur. But the saboteur had methods that were dangerous, dark, evil... This is Harlequin Intrigue #80, December 1987.
