Two nice battles but?
Not the best but not the worst military science fiction. The stock characters aren't shining examples of their types but also aren't beastly.
The aliens aren't given much description and the human government isn't described at all.
The human race is defended by an all American fleet with all American names as standard. A reader/writer almost started a comment war with me in defence of this cornerstone prrmise. He even found Wikipedia proof that non Anglo surnames would not be represented five hundred, a thousand or three thousand years from now. To feel The need to defend those suppositions is weird. This writer does have a token Japanese marine which is better than a lot of these stories.
There isn't much substance to this book but I am going to see if there is another book to explain some of what is missing.
