This is my first written review.

I come to this book from a unique perspective, being that my wife is Korean and we have 2 children (boy 15, girl 12) and while my wife has had some health issues in recent years, thankfully she is still with us. So while I can't exactly empathise with everything Michelle has gone through, I can certainly relate to a lot of it.

The long and short of it that this is a very personal story, I've seen other reviews noting that it feels almost too personal, but I imagine it was a cathartic exercise for her to write this and I applaud her for it.

Not the longest book, I finished it within about 5 days, and felt connected to the story right from the beginning having had similar experiences of Korean culture, firstly through my wife and then vicariously through the children.
Though we aren't based in Korea, I have visit 5-6 times over the last 20 years we've been married to visit her family that are still there, so can easily recall similar scenarios that play out in the story.

I think it's an excellent book and very easy to read, moreso if you have something to relate to it. I've now recommended that the rest of the family read it, starting with my wife, as I'm hugely curious what they will get out of it.
I'm also hoping ours kids take some lessons from it, namely appreciating the sacrifices of their mother, and putting the effort in now to learn 한국어. We also tried when they were younger, but esp. now as teenagers it seems like such a pain in the butt to do, but will be so worth it when they are older, should they decide to visit Korea again one day (I've also been very slowly learning on and off over the last 20 years...so understand the struggle, lol).
