I am not particularly a devotee of short stories. However, Alvarez is indeed a highly proficient writer. I chose to read this because I had a requirement to read a book of short stories, and I was quite enamored with the title and the description. Nevertheless, personally, I initially obtained it under the impression that it was a novel. And if it hadn't been for that specific need for short stories, I most probably wouldn't have delved into this book. Instead, I would have sought out something else by Alvarez.
Another aspect, which I am certain functions on certain levels, is that it progresses roughly in a backward chronological order. There are three sections that span different year ranges, moving backward in time. I didn't have a great deal of affection for this particular feature. Additionally, since it consists of short stories, it felt rather disjointed. This is because, for me, that's precisely how connected short stories tend to come across.
In summary, the writing itself is of a great caliber. However, I don't have a liking for this format or the way it has been structured.
