I started reading this on audiobook, but didn't get very far as I found I wasn't able to keep track of the myriad characters. Once I switched to a paper copy, that was easier, though I did find myself thinking, "who?" about a couple of characters in the penultimate chapter when a number of the characters are all in the same place at the same time for the first time.
I found this hard going at first, even with a paper copy, but persistence paid off and I liked it more the more I read. I sailed through the last 150 pages or so in a day. I found it was more like a series of short stories, maybe even "character sketches with development" than a conventional novel, but as most of the characters were interesting and engaging that was not a problem. I liked how their stories overlapped and intersected without it being to obvious - although the epilogue was maybe a little bit too good to be true. (Having said that, I both saw it coming, and was glad when it did happen.)
The writing style, eschewing capital letters and conventional punctuation was - odd, but once I got used to it, it seemed to add to the stories. I think it made it feel more like someone was telling the story about someone they knew, rather than writing it down. It also made it more personal and realistic as the characters' own stories, even though they were written in third person.
Thoroughly enjoyed this. Recommended.
