I really liked the series! Mr. Nuttall time and again reminds us that alien minds may not necessarily think as humans do, in fact will not think or act in that manner. These ideas we can certainly apply with the differing cultures across the globe, just as the colorblind, racially neutral, libertarian tenets of the Solar Union have much to offer us today. There is plenty of action, although the technological progress the Solar Union makes in such a short period seems a bit unrealistic, and the Solar Union's industrial capacity to produce the weapons used would require mountains of resources and capital beyond imagination. Again, minor items since this is science fiction......
As Frank Herbert did in Dune with Baron Harkonnen, Mr. Nuttall provides us with an indisputably evil, but very capable villian in Princess/Empress Neola. The good guys, Mishiko, Hameeda, Martin, and to a lesser extent, Steve, allow us to share not only their actions, but their thoughts and motivations for what they are doing and saying.
While one could read this book as a stand alone, having read the first five of the series was a huge help with the characters and the overall themes. Mr. Nuttall does a good job with knowing his audience, using terms and phrases most readers can understand. A gentle criticism would be the need to weave in the explanation of the acronyms and abbreviations. Some may not know what an MEU or RV point would be.
I also enjoyed Mr. Nuttall's after words. He seems to be prescient, considering when they were written, with much of what he has outlined coming to pass today. While this is my first review of his work, I have read several other books he has written in other series, and have enjoyed them as well. I look forward to reading his future works.
