‘Next’ tells us stories. Horror stories of what might happen if genetic engineering is commercialized. If genes are played as a fiddle by the hunky dory capitalistic techbros. The book is thrilling. It is engaging. I docked out stars because it had so many parallels running that it is difficult for the reader to keep all of them in mind. And the science is a bit off at times (there is NO one gene that codes for one trait or one behaviour - it is extremely COMPLEX) but I think it was partly intentional by the author to make the point that scientists can be wildly unethical in exaggerating their claims and discoveries.
It’s not equal to Jurassic Park in its quality but is still a good read if you are a fan of some racy science fiction thriller.
