3.5* mebbe 3.75 hehe. To stay spoiler free I liked the ideas presented but not necessarily how they were presented. I felt some things happened just to move the plot forward, a bit too much synchronicity or simplified timing of events than I'd have preferred. After also reading Stephensons SevenEves recently my idea of orbital mechanics has been refined enough that it amazed me how easy space seemed to be to work in. There was also some character tropes which both was overplayed and sometimes sojourned in too deeply.

Really though I can wipe all of that aside. It was a fun ride, I really enjoyed some of the philosophizing and ideation therein. There was a myriad of things that could be possible and that brought those elements home vividly even more.

With how it ends I was both surprised--and in both a satisfying and unsatisfying way--which makes me really ponder what the last book could be about. I didn't grasp enough allusions to get a firm grasp of it.

Oh well. Enjoy it for what it is and from where it is coming from. I did.
