A key to paradise isn't the same thing as entry.

After a tumultuous childhood, Roy Fernsby now runs a quaint London coffee shop that his friends frequent, cycles on Sundays . . . and keeps his distance from romantic relationships. Though Roy's charming and well-liked, being single suits him-if only because it helps him avoid the sting of abandonment. Besides, Roy likes his life exactly as it is.

Then a lawyer in Hawai'i calls Roy to inform him that he's just inherited a beach house in Nalu from his grandparents. There's just one problem: a former foster child, Roy never knew he had grandparents.

Roy doubts this newly discovered "family" ever cared about him. But a tropical island-complete with a beach house inheritance-beckons. He takes a chance and flies to Hawai'i, expecting to stay a week and sell the beach house. Fast. What he isn't anticipating is the resentment and painful childhood memories that resurface as he uncovers the roots of a close-knit family he never knew he had. Why didn't any of these folks, whom everyone adored, look for him?

Then he meets Amy, a former New Yorker and single mother who works as a snorkeling guide. Though the pair are from opposite worlds-literally-and neither is looking for a relationship, their connection is instant, and they're soon spending a lot of time together.

Roy tells himself that Amy's only a nice distraction, even as he falls for her. But Amy has her own secrets . . . and a hidden agenda that involves Roy and his beach house.

As Roy grapples with life-changing secrets regarding his past, he must make difficult decisions about his present: Can he embrace his roots and let go of resentment? Can he trust Amy? Can he stay and seek the truth about where he belongs-no matter the cost to his guarded heart?
