For me much resistance at first but in the end up late not being able to put it down. Perhaps fueled by emotional energies ready to demonize old money and other elites. The Times review is on the money. (https://www.nytimes.com/1992/09/04/books/books-of-the-times-students-indulging-in-course-of-destruction.html), although there might be at least a redemption light for one character.
The length of the book might point to respect for the author's first work, which this is. Like many other works, the concluding pages update the reader on subsequent developments in the life of the characters. That this extended to some that played very minor roles is indicative of something.
Full of food for thought but I wouldn't go as far as one has here to planning an annual read.
