This book was hard to put down! I must speak of the performance of this audible book first. We have a relatively good narrator but what brings the..Show More » book to life are the specific female and male voices for each of the characters and the background sound effects that bring each scene to life without actual visual. This is the first I've experienced and it's like experiencing a movie with everything except visual input. The story itself was entertaining and certain aspects of it showed in-depth understanding, research and development of scientific issues/ideas from which flowed a believable story. A few points are taken away for the predictable aspects of the story and the over indulgence and dull delivery of erotic parts. Generally I found the book very interesting and endearingly romantic. I also think there is a lot especially on the political front from which further books in the series can build upon. I can't wait for the next book in the series!
