Query: Fair but not Good

I have to agree with a majority of the observations that Matt Kaufman made. I will not repeat his observations but will add some of my own without revealing some good plot twists.The most obvious is why the nuclear option was not discussed anywhere in the first book. I also do not think the advances in military culture (large numbers of women in high places and on subs) and technology could take place in just another 15 years, maybe 40 years from now but not by 2021. The twist at the end is also hard to fathom, but I will let you decide. The book is an interesting read, but I am not sure if I will read the next one at full price. 2.5 stars but that is not an option
