Oof this one is a lot. 
This is so well written, and so deep. But it's one that I find hard to connect with and uncomfortable to think about. Murakami is always exploring depressive/traumatic taboo in his novels but this one takes the cake of any I've read so far. It was extremely difficult to read chapters 16, 29, and 39. I would put a huge TW on those particular chapters. If you haven't read Murakami before, then go into it like you would a horror genre. He does not write horror, but he sure isn't afraid to get icky. 
Also, after finishing, I'm still not really sure how some of the pieces connect or if they are even supposed to. The beginning was very five-star for me but it went in a different direction than it appeared to be headed at first.

I didn't love the experience of this book but it is still good, if that makes sense. It's hard to say I recommend it because of the content (

incest, rape, murder, violence, and weird fixation on the main chatacters genitals.

) but if you can handle it and want to get into it, then it's one to take your time with. I would not suggest it as a first by the author. But if you like his other stuff then definitely read this! 

My favorite bits include the idea of a lighter shadow, conversing with cats, and the less-human inner self taking the form of a crow. 
My least favorite parts include the entirety of the three chapters mentioned above.
