I'm so happy I stuck with Gravitational Attraction. I had a hard time in the beginning getting into the story. But once in, I was in all the way.
Kudos to A Martinez for making a love story but not losing sight that this is a science fiction novel first and foremost. The sex didn't get a chance to overwhelm the story, thank goodness. I found the aliens intriguing and wanted to know more about their way of life.
