I loved the book. The battles in the book are full of variety, from a legal battle, to a simulated space battle, to a violent infiltration of a marine base. Each has its own intensity and stakes involved, and all are well narrated.
If a book doesn’t teach you something, either something that’s definitely true or something to consider, I personally don’t think it’s a good book. The author of this book didn’t write the book with an agenda, but slips in several things that we can learn from, or at least think about. Some of them are political. Some are about human nature, or other subjects.
