St. Gregory is the fictional island. That is St. Maarten. It is not a bad, depressing read. My husband, Dave, who NEVER reads fiction, absolutely loved it. He loved reading about places we know and have been in the book. The drama is unreal. I read it twice already. It is hard to find. For sure. I downloaded it on my ipad several years ago. It can not be downloaded now as far as I can tell. I bought the paperback on Amazon, but it took a while to find. I don't know why. The author lives on St. Maarten and England it says.
