Only One Survivor?

A lightish read about a group of five folks who are "invited" to board a tour boat but find themselves abandoned on a supposedly-deserted island in the middle of nowhere.
They are forced to fend for themselves and soon find out that only one of them is expected to survive!
The book dwells a lot on the central character and her thoughts about the dying relationship with her workaholic spouse but we learn little about the other survivors.
The book has a subtle but rather incredulous twist at the end.
