Although this is my first stab at science fiction romance, I found this book to be decent. The characters were believable and the situation well set up. The world building could have been better, but that's a problem I also have with paranormal romance. At least it didn't feel as if McBride was doing the world building while actually writing the novel. Some day someone will write a paranormal or sci-fi romance after having developed the place in which the story takes place.
If you're looking for something short, sexy and sci-fi, then this is a good choice. I would like to see another book with these characters.
