It's in His Kiss (Lucky Harbor, #10)

ONE KISS CAN LAST FOREVER
Becca Thorpe has uprooted her life and escaped to the beach. Now's her chance to get away from city living, throw caution to the ocean winds, and live in the moment. Especially if the moment includes the deliciously sexy surfer she meets shortly after arriving in Lucky Harbor. Something about the dark intensity of Sam's eyes and the thrill she gets at his touch convinces her to stay awhile.

Boatbuilder and investment genius Sam Brody is a self-made man who knows how dangerous it can be to mix business and pleasure. But he can't resist offering Becca a job just to hear her laugh and have her near. Yet when her brother comes to town asking for help, will he tempt her back to her glamorous life in the city? Or do Sam and little Lucky Harbor have a chance to win Becca's heart?
