Little Fires Everywhere

This is a genre I tend to avoid because real life-adjacent stories are not usually engaging enough for me, but the hype around this novel a few years ago was intense, and I was landed with a copy through no fault of my own. I am currently making my way through a long progression fantasy series, and needed a breather, so I decided to just read this as a break. 
Right off the bat: I really did enjoy this, despite my preconceptions of the genre. I was pretty much hooked from the start, and finished in two days. The characters are well written, with complex emotional worlds, and histories in which they can be interpreted as both good and bad people. They are in the grey-zone in between, and that is refreshing. 
I had a look online to see how much $10,000 USD in 1982 would be worth now in 2024, and the sum is about $32,500 USD (??25,600 GBP). I personally would not volunteer to carry a child for someone and birth it for even ten times that amount, and that's because I don't think permanent changes to my body are something I could put a price on like that. I am not sure if this is meant to show Mia's sheer desperation or whether the author thinks that is a reasonable, believable amount for a surrogate pregnancy.
note: I did just Google it, and the prices do appear to start at $35,000 for surrogacy in the USA, and about ??10,000 in the UK. I find this unbelievably cheap.
