Faction Wars has been referenced numerous times in the previous books, and we finally arrive. It is not easy to review the book without spoilers, but I can try. In the words of Carl, “We gain things, and we lose things.” And in war, that is always true. Friends are lost and gained, and hard choices must be made in the interest of survival. More lore about the outer world is introduced and I’m not sure if the AI is becoming more or less insane. Certainly just as dangerous. An excellent book in the series, and I highly recommend it if you’ve enjoyed the rest of the series!
