Novel set in New Zealand, by an American author.

"Everyone needs to be rescued sometimes.
Everyone but Hanna Montgomery, that is. She just needs a vacation. Three weeks in New Zealand to sort out her life, figure out what she wants, seems just right. Oh, and to relax. She should definitely put that on the agenda. She certainly isn't looking for a fling with a professional rugby player, no matter how attractive he is. Hannah doesn't do casual. But maybe just this once...
Drew Callahan is happy to help Hannah find all the fun she's been missing. But as much as he's shared with her, he's kept one very big secret. And learning the truth, now that she's back home again, has made Hannah more wary than ever. Drew knows that she's right for him. But how can he convince her to let down her guard enough to explore what they could have together." -- Back cover
