Another excellent book, well researched.

Some might find it a little slow and too painstaking.

Upgrade is a 2022 novel by Blake Crouch. It is his tenth stand-alone novel …

The novel explores the ethical and existential ramifications of genetic engineering, set in a near-future world where humanity grapples with the consequences of advanced human genetic enhancement. …

In the late 2060s, Logan Ramsay is a law enforcement official working for the Gene Protection Agency (GPA), an organization established in the aftermath of a global famine known as the “Great Starvation”, which resulted from an attempt to genetically enhance crops.

This catastrophe, which caused the death of 200 million people, was led by Logan’s mother, geneticist Miriam Ramsay.  …

It was thought that Mom died — BUT was secretly working on a genetic “upgrade” to improve our species, hopefully helping us last longer on earth.

The plot has as much to do with genetics as it does the relationship between Logan, his sister, and their Mom.

I did like the end of the book. Nice touch, Blake.
