Their Song Unending — Anna James

A secluded island, a timely plane failure, and voila: Logan Addison, conservative investment counselor, was stranded on romantic St. Cat's with Justine Hart, the flamboyant singer he'd desired from afar. And soon calamity led to caresses...

But back in Manhattan, Justine's stage moves were light-years apart from Logan's Wall Street maneuvers, and disaster was waiting in the wings. To save his free-spirited lover from a commitment she'd always regret, Logan would have to teach Justine their own private love song, then set her free to sing it...even if it broke his heart.
