You don't expect those who reinvent the wheel to be awarded the patent.
Okay, let me step back. While I have serious problems with this book, it was actually a surprisingly pleasant reading experience. That is due in some part to the magic of low expectations, but it is also because the characters Charnock crafted are engaging. I might have liked this book if I could have read it without any context.
But as a piece of science fiction, it fails, doubly so as an award winning piece of science fiction. I can see the reason why the director of the Arthur C. Clarke award called this "science-literate fiction" rather than science fiction (though even that may be overstating the case). Frankly, this reinvents the wheel. What do I mean by that? I mean that the author is acting as if the genre concepts she's working with are completely novel. I will grant that I'm not aware of any books that focus on pregnancy an parenthood, but there are plenty that raise the technology and situations that this books turns it's attention to. The technology is nothing that the author had to dream up, some of it already halfway exists, and it's all mentioned so quickly that Charnock doesn't have time to add anything. The problem is that this book acts as if all this is something science fiction has never dreamed (heck, half the time it feels like it's try to invent science fiction). Ultimately this book feels like it's throwing in the future and technology to get a better stance to philosophize.
Another wheel this book reinvents? To quote the back of the book "[W]hat does it mean to be a parent? A child? A family?" The basic answer isn't anything new to, for instance, families that adopt or those who know that. While genetic lineage has some influence on a child, parents and children are defined by the act of caring, the act of rearing, and so on, not the circumstances of birth. Yawn. Seriously, that's enough to win a major science fiction award?
And it gets worse. This book is told in 3 periods. The first is 16 years down the road. Then 50 more years away, finally another 36 years. That earliest section hasn't changed much from our world. Oh, the branding of single parenthood has changed a bit, a few things are more common. We have hints that polyamory might become more acceptible by 2034, but zoom out to the middle era and one couple maybe has some sort of open relationship, but really seems more like the characters have an on-again off-again relationship and otherwise the relationships are traditional. We have a bigender character (the gender isn't stated, so I'm guessing at a term, but certainly someone outside the gender binary) who seems to have a little bit of an easier time than they would today by a bit. We have an asexual, maybe aromantic character whose bisexual. None of this feels even near futuristic but that's what it's supposed to be.
Looking more broadly and in the later eras, if there were queer identities down the line, I missed them (and maybe that's possible, I had to spend enough effort as the vignettes jumping around trying to figure out/remember who was who and who they were related to--at the very least they have a tiny role to play). There's no one else outside the gender binary, no queer relationships. And, heck, the bisexual character seemed more to have had a 'phase that she went through' than to be depicted as really bisexual (I will grant that the book takes a moment to defend the characters queerness, but it still disappears), the asexual character is described in insensitive ways (I will again mention that the book takes a moment to defend her against the older generation, but still). And something seemed a bit off about the depiction of the bigender character (though I can't honestly say if the author didn't do the research or knows someone who experiences gender in that way, so I can't come down strongly here). All together, it's not surprising that queerness gets erased in Charnock's future.
Honorable mention for ridiculousness? A character in 2120 pushing a goal of becoming a street food vendor selling crepes as if she's discovered the future. Seriously? That exists. Where I live.
Also, incredibly bougie. Seriously, this focuses so much on how the middle class would be affected. The lower class comes up a bit, but those characters are introduced through the eyes of one of the bourgeoisie.
Edited further: I meant to knock this book another way. One of the characters who gets unexpectedly pregnant should have (judging solo by her internal monologue) probably have gotten an abortion. Even more (again, judging by her internal monologue), she shouldn't have stuck with the genetic father, or at least she shouldn't have tried to transition their relationship 6 weeks in from something very casual to a long term relationship with parenting involved. But it did all work out in the end (in the book), I guess because having a baby makes everything easier, or something?
