Query: Not impressed

To be honest, I'm rather puzzled by the numerous positive ratings of this book. I figured I would try it out, as it was free for kindle, but I was pretty disappointed.The romance in the book develops far too quickly and comes off as entirely unbelievable. Many of the plot points are silly and are meant to be creepy rather than realistic. And the protagonist is incredibly foolish despite the fact that she is supposed to be a highly respected anthropologist.All in all, I didn't buy into the story in the slightest and was thoroughly put off by the ending, which posed more questions than it answered. I get the feeling that the five star reviews come from people who don't read quite as avidly as some and don't know the difference between good sci-fi and bad sci-fi.
