Imagine that you see something on a cruise that is pretty unbelieveable. This is what happens with the main character in this book, Lo. She's having a crappy life at home, so she decides to go on a week long cruise. Telling more would ruin thisbook, with all the twists and turns, but this wasa really goodbook over all. Lo wasn't the best of characters I've ever read, but I didn't particularly dislike her. The story moved along at a pretty good pace, and it actually did leave me guessing a few times.
Another thing that kept me guessing was why this was a Psychological Thriller. Yes, there were some mind games in the book, but I guess I'd have put this book in a who done it type mystery, with some Psychological elements thrown in, for good measure...
