Matchmaking for Beginners

From the first chapter you know the end. You just don't know the how. It's a compelling read about a newlywed couple on their honeymoon in Bora Bora where they come across a plane crash while scuba diving. They retrieve a briefcase and find a treasure trove inside which they keep. So it's more or less about a seemingly decent and moral couple who find themselves seduced by the lives they could have if they took advantage of this windfall. And they do. That's the how. I though it was an interesting tale and was totally taken by the ending. On the con side, I found it somewhat belabored a bit boring throughout the middle.
