I was very surprised by this book. I don't read that many books that leave me feeling slightly uneasy, but this one did - in a good way. It was fascinating, well written, and appealed to my inner-geek greatly. A slightly unusual spin on the usual sci-fi offerings; well worth reading. Read in one sitting - couldn't fathom putting it down!
I'll admit I haven't read the three books before this one; I will, however, be purchasing them now. This book did stand alone quite well, but it will be interesting to see whether I revise my review at all upon completing the previous three books. Glad to have 'found' a new author I enjoy!
