Very fun, and big thoughts, too — who should get access to enhancement, what makes us human, could we engineer our evolution into a new species. Glad to see more neuroscientists in action -- and some of them are good guys!
I usually like more character development and subtler dialogue, but was willing to let that slide since the science and the tick-tock thriller part were so good. Didn't need the epilogue.
The text has a lot of italics, alternate font, and spacing between points of view that did not transfer well on my Kindle copy, so better if you can get it as a library (physical) book.
