I read 24% before abandoning this book. The world-building was weak, with cartoonish nomenclature, preposterous geopolitics, and arbitrary social engineering. This structure wasn't sturdy enough to support the very real issues that came up in the setup and plot--classism, racism, privacy, etc. Taken together, all this made for a world that didn't feel real.
Character development was weak, too. For some reason that may have become clear later in the book, the narrator was the character least involved in the action. We learn of everything at some distance. With their inner worlds not fleshed out, the key characters felt thin. Much of the dialogue was stilted. At other times, deep emotional moments would resolve with platitudes. Again, taken together, these factors made for characters that didn't feel real.
