This is a gorgeous, gorgeous book. (And I’m not talking about the inhumanly lovely face on the cover.) Westworld, HUM∀NS, Black Mirror—if you’re a fan of any of those, this universe will feel familiar to you. Then again, it will feel familiar to you if you live in the western world (and probably most other places) at all right now.

So then, what’s it about? Well, let’s try a little philosophical exercise. 

I don’t think that most people would argue too much with the proposition that if you lose, say, a foot, and it’s replaced with a prosthetic foot, you’re still you, and still human. Still true if you lose both feet, or both feet and both legs. And the recipient of a donor heart or liver is obviously still human and still themselves. Got a tattoo? Still you. Skin completely covered in tattoos, 27 piercings, and no appendix or tonsils? Possibly an unusual specimen, but definitely still human.

All right, but where does the line begin to blur? 

Let’s say a pair of twins were both born with numerous potentially fatal birth defects, and at a certain point in their lives, when they’re in their teens, one of them begins to suffer from cascading organ failure. There’s no question that this twin is going to die; only massively invasive medical technology is keeping her body even minimally functioning. Meanwhile, her twin continues to suffer from numerous major disabilities and it’s medically certain that he won’t live past his twenties. At best.

Unless. Unless his twin’s organs are harvested—the ones that are still functioning—and used to replace or repair his. This has to be done while they’re still in some kind of condition to do him some good, of course. And it has to be done using new technology that allows her organs to be grafted to his—stem cells, 3D-printed artificial tissue, CRISPR gene editing, what have you. And this is truly major surgery. A really significant percentage of this teenager’s body, going forward, will have once been part of his twin.

So… is he still himself? Unless his brain were being replaced, most people would still say yes. Likewise to his still being human… though some people might call him a monster. But they would probably mean that metaphorically. Mostly.

All right, then. What if, a couple of decades later, a teenager is in a terrible car accident, and half her body is completely destroyed, and she doesn’t have a dying twin to provide her with donor parts… but she has really top-notch health insurance and access to the world’s best medical technology. Which can replace literally everything that’s been damaged or destroyed with synthetic and/or mechanical parts. Is she still human? Is she a cyborg? What does that even mean? And how will that affect her social life when she goes back to high school?

It goes on from there. What happens when we start deliberately modifying ourselves with parts of other people, or even animals? What is it that makes us human, what makes us other, and where does morality lie in all of this? Where does it end? Centuries, millennia from now, where will we be? Will we even be "we" anymore?

If any of this is even a little interesting to you, you should read this book. It’s written with such clarity and curiosity and understanding of what makes people tick that you will find yourself empathizing with points of view that are deeply inimical to yours.
