The book has 6 or so stories that are loosely linked via themes. It's nothing to get in-depth about. Sources also clarify this -- not even remotely interesting. These stories differ completely. I'm referring to writing style. Which can be categorised into good, and bad. Tolerable, and tedious.
I haven't read anywhere that this book is well written, there's so much praise for how it's written. I call that pretentious. No matter how much free time or a devoted reader you are, if you read hundreds of pages just to call it "clever" rather than enjoyable, I call that pretentious... and that's giving it something.
The cover and the awards might make this a good book though.
