Picks up from prior book and we are in civil war in our solar system - or a terrorist action, depending on which side wins. Less escapism for me in this one and more sadness. Book is still written well and at a different time I may have enjoyed it more.

Instead of only 4 povs, we get 17.
8 of them are people we have had as a main pov in prior books and 5 as people who we know from prior books.
