Natalie has always been the fun Grant sister: the one with the constantly packed suitcase and the zest for life. But this carefree existence is wearing on her. When her oldest sister, Olivia, invites her to Lavender Island for three months, Natalie jumps at the chance to look after her niece, prove she’s not irresponsible, and take a much-needed vacation from men.

Her “mancation” takes an unexpected turn when she spots a group of sick sea lions and calls on microbiologist Elliott Sherman for help. Elliott is everything Natalie is not—quiet, studious, and geeky. Yet there’s a simmering sexiness under those glasses that she’s quick to notice. And Elliott finds himself taken with her gorgeous free spirit. Despite their chemistry, outside forces threaten to keep them apart—including a secret Natalie has never shared. Can the allure of Lavender Island and its quirky residents open her heart and lead her to lasting love?
