This is a very short tightly written hard sci-fi genre novella that is totally worth your time.
This is not a book about anything even if it tries to get there. Yes, there is an ethical question raised at one point but it is so quickly rendered moot, that no one really has to wrestle with it… or rather, Klara doesn’t wrestle with it, Josie doesn’t wrestle with it, and the parents who do are so ancillary that the reader doesn’t feel compelled to give it much more thought past “/shudder, yikes!” before moving on.
I really liked this trilogy. The 1st book is adrenaline, the 2nd is cerebral and the 3rd is ramifications. All are enjoyable and I really appreciate the nuances that Ness adds in. The stakes ratchet up, the tension increases, the death toll climbs (even though the saddest death is in book1 -I am still upset by it-) and the tone gets darker as the series continues. It is a lot like growing up.
It did keep me interested even if I pretty much figured out the shocking reveal early on (to be honest I had it pegged as one of two things and the thing it wasn’t is far darker and way more sinister than what it was, so I guess you should be glad I wasn’t the one writing this).
I didn’t want to put this book down. I was curious up to the very end.. And then there was an epilogue of sorts that made me hug myself with happiness.
