Reading these books is a little like using crack, without all the nasty side effects. He gives you the first book in the series for free and from that point on you are hooked. I have read all the books in this series and am eagerly awaiting the next installment. This is great science fiction but will apeal to many non geeks due to the wonderfull characters, multiple plot lines and breathtaking action scenes.
Try the free first book and you will be addicted as well.
This is the last book in the series and it wraps up all the story lines nicely. As with the other two books in this series my life was essentially on hold until I finished. While it is possible to read this as a stand alone book it will make more sense and be more enjoyable if you read all three books sequentially.
As a final encouragement to you prospective readers these books were almost twice what I like to spend on a book and yet I still bought all three, there that good!
