Separate Cabins [EPUB ebook] 

In the four years following her husband’s death, Rachel Mac Kinley battled her loneliness by building a thriving business. Then, on a vacation cruise off the coast of Mexico, a travel agent’s error placed her in a cabin with dark-eyed Gard Mac Kinley. Delighted with his beautiful shipmate, Gard felt they shared more than just the same last name. His passionate kisses seemed to burn a promise of forever into her heart. But even as her long-denied desire blossomed in his tender embrace, she feared she had fallen desperately in love with a man who wanted nothing more than a shipboard affair.
