"Important"
May be the first truly important book on the subject of sex this century. Ground breaking. Read this book.
"Classic... Just Classic"
This is a wonderful character driven sci-fi that in many ways feels like Heinlein's work. This is a wonderful little novel. Really... this is worth the credit.
"Historically interesting ... but manipulative"
Interesting book. Fun. But, has a tendency to leave out some very important historical details. Extremely white washed version of the history of the CIA. Paints some people who where clearly villains as patriots. If you're going to read this book... spend some time on "Legacy of Ashes." They balance each other.
"Kind of Early Heinlein-ish... Only offensive"
If you like good sci-fi, and hate the liberal media... then this book is for you.
If you have any world view that differs from that found of Fox News... Then this author is going to spend quite a bit of time calling you a "Socialist." Actually, he is going to spend the entire book ranting about liberals.
The expression of different ideologies within fiction can be a very good thing. Spreads the brain and expands your world. But, when a book seethes with hate for one specific group of people (ie. people who's opinion differs from that of the author), it becomes offensive. This book is a good example of an author exercising his first amendment rights. It is also an excellent example of bad business sense. Rule one: if someone is willing to buy your book(s), don't spend the entire book insulting your potential customer. Limit it to a couple of paragraphs at the very most.
I subtracted only one star for this mistake. I don't know if I will buy his next book in the series.
"Needs work"
I'm afraid that this book really isn't very good. The characters are so 2 dimensional that they are almost 1 dimensional. Don't bother. Try one of his later books.
