When I was around two thirds in, I started idly concocting a review in my brain, about how the almost surreal elements and characters was what gave this narrative such a verisimilitude. Cue me over the 80% mark, just going to search for a detail, and finding out this is nonfiction. Sure, there are artistic licenses, but in essence?
I love it when knowing absolutely nothing about a book pays up in such ways.
As I mentioned previously in an update, the general tone reminded me a lot of latinoamerican writing. This has a lot to do with the conservative (and quirky) societies that brew in relatively small, isolated towns. You have the sedate and beautiful surface, and the decades/generations long ugly undercurrents. Everyone "behaves" in public out of a certain need for society and peace, and whomever "pops" may as well go the whole nine-yards and wear it like a flag.
So, that's basically the aim: to illustrate Savannah. The plot as it were serves the theme. We go into the deep ugly undercurrents. Almost every ugly you can imagine. Sometimes you are enraged and amused at the same time from the sheer hypocrisy rampant. I spent most of the book in some queer state of entertained stupefaction because it is so grotesque you almost can't believe it. But you do. You recognize it. It is your hometown.
