The plot is interesting and there were some good observations about life in general and Indian middle class life in particular. I was, however, confused and put off several times by what appears to me to be grammatical errors in this book. The novel is the place where some of the most considered writing resides - and readers choose to turn away from the rubbish of daily life (social networking, reality TV shows) and in my view it is important for a novel to be more discriminating, more worthy of a reader's time than an article in a newspaper.
I'm no grammatical pedant and am young enough to understand that the way we use English changes over time. My grammar is certainly not very good either. However these errors in a novel - such as treating a common noun as a proper noun - grated with me. I grew up in India and this is a typical Hinglish way of using common nouns in conversation, although I find it alarming in a novel, especially as part of the narration (and not as a piece of dialogue from a character, which is fine of course, because a character can speak how a character needs to speak). "It was seven when he reached office," is one sentence halfway through the novel. The lack of a "the" before the word office, is one small example of the grammatical errors littered throughout the book.
English newspapers seem to fall over themselves to praise every so-so book from India, each one hailed as a "new generation" and as a "satire on the caste system." Perhaps England is still in love with the romance of Empire, and sometimes fetishises Indian fiction, whether is is good or not. Although I do like it that England has an appetite for Indian fiction. Tired cliches abound - a woman whose husband has admitted to an affair thinks to herself, "It felt as if someone had died." Much later, as a couple are going through a confrontation, the rain "grows violent" outside, matching the weather to the mood.
All in all it's a good, light, urban plot and touches on the Indian IIT (India's Harvard)graduate's typical obsession with science above everything else. It's a first novel and that's obvious too. It's also not sentimental and it's intelligent, which is great (unlike the un-literary 'gap year' fiction that was Shantaram). I'd just like British critics to judge Indian fiction in the same way as fiction from England. If a book of this quality was written in England, in my view, it would certainly get none of these inane, undeserved pieces of praise it has received. Sloppy praise damages the faith of the reader in reviews and ultimately in the novel itself. If you want an intelligent recent urban Indian novel, I'd recommend Amit Chaudhuri's The Immortals.
