I love Blake Crouch. This book was PAINFUL! I started it twice. I have never finished it and will never finish it. What is actually happening? We get it! He is superhuman. His sister is superhuman. Endless descriptions on how special he is is so overdone. Move on already!

Always enjoy a Blake Crouch novel but this one fell short for me vs his other books

I get it. The main characters turn super smart wiow wow…. Yawn. Wow. Never read that before And what grand revelation do the characters do either it? Same short term self interest activities dumb people do… Not clever. Not new. Not worth reading

Could not put this down. Terrifying in that it’s all so plausible.

A fun read but with high end science that I needed an “upgrade” to understand most of the time! Still, I learned something which was pleasantly unexpected

Great book! loved the story and ideas it provoked. Couldn’t put it down. Another great entry in Blake’s growing catalog of fun and entertaining rides! If you like Andy Weir and Blake Crough go read this book!

This is my third Blake Crouch novel I own and have read - I am literally writing this minutes after having finished this novel - and he continues to be one of my favorites out there. I do not have many sci-fi novels, and I am as of recently exploring a little more with book genres, but Crouch's Dark Matter was my introduction to sci-fi and I have been hooked ever since. I love how well he continues to make these sci-fi novels while each still being very independent from one another. This story really stands out to me compared to his others a great way, and actually reminds me of classics like 1984 and Brave New World; This novel has a very relevant theme that while fictionized, seems extremely relevant and real in today's world and where our world is headed. Crouch definitely did his research and had great contacts to help him with this novel. This novel very much makes me feel like it is a very real future for humanity rather than a completely fictionalized story; What is even scarier is it doesn't seem like this is a far-distant future. Regardless, I highly recommend this book, especially those with any type of science background. LOVED.

I haven’t enjoyed a fiction book in a long time but I loved the his book and couldn’t put it down. Read it in two days.

There was science and relationships and futurism and ethical dilemmas and suspense, all in one book. Crouch’s writing style is comfortable to me, and he explains the science well.

Crouch has definitely mastered the Art of the Page Turner. With this book as with the Pines he can engage the Reader with his plot and characters without being cute or cheesy. The good thing about Upgrade is that it is a Sci-Fin Novel that dangles enough Genetic and Weaponry arcana to establish its street cred with lovers of that genre without bogging the rest of us down and keeping us from enjoying the suspense. And there is plenty of that. While I found the finale less than satisfying, I enjoyed the journey and the geography it traversed. I do wish that he had left the sentiments of the epilogue to the Reader so I’ll limit my praise to Four Stars. ****
