What happens on a cruise ship... doesn't always stay there.

Katie Ross thought a Caribbean cruise would be the perfect escape-if only her cheating ex and his new fling weren't part of the bridal party. With no rooms left on the ship, Katie's forced to bunk with Dominic Price, her sister's fiancé's best man and her personal nemesis. Dominic is gorgeous, insufferably smug, and-unfortunately-her only lifeline against her ex's antics.

When Dominic steps in as Katie's fake boyfriend, the lines between pretend and reality start to blur. Amid sun-soaked days and cocktail-fueled nights, their witty banter gives way to electric chemistry. But as sparks fly, Katie wonders: is Dominic really playing a part, or is there something deeper behind his irresistible charm?

Can Katie and Dominic survive the cruise without sinking their hearts-or will they discover a love worth navigating?
