It's a very interesting premise, but overall I felt it was very predictable. Did anyone really believe that Martha Quinn's Island was anything more than a trap? Or that the baby was going to turn out to be a girl? What I felt was unpredictable was just how quickly and easily obstacles were overcome. Most of the book moves along very slowly, and then when things start to get exciting the narrative gets rushed, only to return to a slow moving part of the book again. It was an enjoyable book, but not his best and not one I'd read again.
