Alec King is rich, ruthless, and old enough to know better. But when a billion-dollar deal hinges on him being a "family man," he makes a reckless move—and introduces his smart-mouthed, much-younger dog-walker as his wife. Ella Reed wants nothing to do with the grumpy silver fox who never even remembers her name—until he offers a week in paradise and a paycheck big enough to cover her dream of vet school. One Caribbean cruise. One shared room. No real feelings. Easy, right? Except Alec isn't just brooding and bossy—he's sexy as hell.
