From Four Weeks to Forever Parasailing. Hang gliding. Rock climbing. That's what hard-driving exec Calhoun Hart had planned for his monthlong Caribbean jaunt. Until a skydiving accident puts a crimp in his plans—and puts him back into work mode. First order of business: fly in a personal assistant. But how's the once-burned bachelor supposed to resist the serene, superefficient redhead who has more than his bottom line working overtime? Justine Walker could do a lot worse than this tropical Eden. And working with Cal is reaping unexpected benefits. Like helping the widow heal from a tragic loss...and showing her sexy, never-stops-to-smell-the-roses boss how pleasurable downtime can be. But once vacation's over, are they ready to take a leap of faith and keep paradise in their hearts forever?
