This is the most emotionally intense book I have ever read. The prose itself amplified the identification, the empathy, the solidarity I felt with the characters. Even though the narrator is of the "omniscient" type, the prose changes the tone, the assumed lens of the narrator as it shifts to focus on different characters. It's as though the "eye" of the reader becomes temporarily merged with each character, with their ways of seeing the world.
If someone reads & enjoys this book, I also recommend reading Pankaj Mishra's "Run and Hide".
