I just finished read Aravind Adiga's 'The White Tiger' last night. It was easy to read, and difficult to put down--I finished reading it in two days, which is very fast for a generally slow reader like me.
It held my interest with the situations he has written about, the characters, and the simple, clean language. His idea is interesting to think about, and the book is worth reading. But it wasn't eye-opening for me as such because the situations described (the dirty, impoverished, cruel and unjust face of India) are familiar and things that I have already pondered and mulled over before (and I think most of us have). But I suppose it could be a revelation for people abroad who have no idea that this is how modern India is, too.
It is a realistic depiction, but it is also focused only on shining a torch on these negative sides, and little on beauty and goodness. At the same time, the book is far from depressing; it has energy, and a strange sense of balance and justice. It shows a way (albeit illegal ways--he makes it clear there are no legal ways), for the poor and downtrodden, of breaking out of the 'rooster coop'.
It didn't move me much or stay with me after I finished reading it, though I suppose parts of it will come to mind when I come across scenes or instances talked of in the book. I rate it 3.5 out of 5.
