As an agent of the Gene Protection Agency, Logan Ramsay doesn’t feel anything different after a raid-gone-wrong at first. Before long, he realizes his genome is altered; Logan is reading faster, focusing better, sleeping lesser, and becoming a more "upgraded" version of himself. Using his newly-formed abilities, Logan is the only one who can save humanity from everything, impending war and the doomed future.

Blake Crouch examines humanity's limits and potential with this mesmerizing sci-fi thriller. Upgrade explores the intriguing dystopia where genetic engineering is illegal, government surveillance is ubiquitous, and climate change has led to widespread poverty and food insecurity. I enjoyed the lightning-paced plot and how the book illuminates what it means to be human through brilliant story-telling. Especially as a scientist trained in this area, books about genetics are one of my favorite types of sci-fi. I don't quite agree with the science itself, but that's me being a bit of a science snob lol. More importantly, I wish the ending were different. But in any case, Upgrade is an unputdownable read for those interested in molecular biology!
