Wow. It's been awhile since a book kept me awake into the wee hours of the morning. Not only was this a well written sci-fi adventure, it was a wonderful romance. It's not perfect, but what few flaws I discovered did not at all hinder my complete enjoyment of the story. It swept me away from page one. I'll be waiting somewhat impatiently for the next book in this series. 4.5 stars rounded up to 5 stars. Highly recommended.
