Barbara Delinsky - A Single Rose (Unabridged)

Matchmaking comes as easily to Victoria Lesser as breathing. Then two of the couples she has brought together decide to turn the tables, and set up a match for her with a treasure-seeking professor who's sailing to Costa Rica. Usually fearless, the intrepid Victoria gets cold feet, and talks her niece, Shaye, into coming with her. The professor shows a little caution, too – he's brought along his nephew, Noah. As the four of them head for their exotic destination, sparks fly between Shaye and Noah, and the older couple can't help but fan the flames.
