Crux

2022 reread
I stand by most of my previous review. This book feels incomplete, where Nexus was a finished story. I did miss the internal Nexus hacking.

Reading these back to back, I also noticed that the author's writing is better in the second book. Looking forward to reading the third book this time!

2014
The first book ended with a different world. This one ends with the potential of a different world and a major threat. No resolution, another book needed - down one star.

That said, Ramez Naam has an interesting concept which is not far from reality. The writing is fast paced and the scenes thrilling. There is less internal Nexus hacking, but then 3 of the 4 major code writing characters from the first book are out of commission.

I will very likely read the sequel, but hope that it ends this storyline.
