I think it's significant that this is the first book I have finished in a long time.

It's good, serious science fiction. With interesting thinking about where our algorithmically controlled social media future might be heading.

It's space war, but not like any space war story I've ever read. Definitely not "rah, rah, go humans!" stuff.

It's not one I'd recommend for every sci-fi fan. But if you're into Philip K. Dick or Harlan Ellison, this is worth a look.
