Here's the blurb:
Duncan MacNeill is a Highlander at heart with a mission—find gray wolf and former stockbroker, Silverman who has stolen the family fortune and is purported to be living in the Grand Cayman Islands. As a Highland wolf, Duncan rarely leaves his native homeland and taking a trip to an island paradise doesn’t appeal. But keeping the MacNeill’s ancestral castle depends on making Silverman pay. What Duncan doesn’t plan for is the American botanist who distracts him from his mission and makes him realize what an island paradise really means.
Shelley Campbell is teaching botany at a Florida college, when she receives an email from an old girlfriend, who’s renting a villa on the island and wants her to come to stay with her. Figuring she can study the old growth forest while she's there, and lecture about it when she returns home, she has no idea the secrets she might uncover. When her girlfriend’s a no-show, a Highlander turns up instead, and she has a choice—share the villa, or send him away and pay full price for the accommodations—which on her teacher’s salary is stretching things pretty thin. Since he promises to be no trouble at all, she lets him stay. And that’s when the trouble really begins!
