I almost gave up on the book, because the start of first story I found a bit depressing. It seemed like a story of "pensioner sex" and I just did not want to read about it. Then the pace and interest in the first story picked up, as it did with the rest of the book.
The stories are about real people in the real US and the characters are interesting, hateful or loveable or just real.
Some stories are almost novellas, and they are all worth reading. Sometimes I had to reread sentences because who is doing what is not always explictly stated, I had to work a bit harder than normal. But that might just be me.
