I've always been a sucker for the hyper-competence micro-genre, and Upgrade is the best example of this category in recent memory.
Hyper-competence is difficult to write well, primarily because readers are unforgiving of mistakes made by hyper-competent characters. Blake Crouch clearly spent time polishing this novel, because there wasn't much that broke my suspension of disbelief – a huge deal in this type of work.
If you're into hyper-competence, gene tech, big questions about the future of humanity, and fast-paced action, this book will be right up your alley.
You can order the book from Amazon here (as an Amazon Associate Compelling Science Fiction may earn a very small amount from qualifying purchases, which helps with server costs). I did not receive any incentives (financial or otherwise) to review this book, but I was sent an early access copy by the publisher.
