Its a great book which tells us how we Indians inadvertently misuse English. I have learnt a great deal from this book and have stopped the usage of words like co-brother, good name etc. :)
The kindest thing I can say about this book is that it's interesting. The author makes some good points about the British-era ridiculousness many English newspapers still use in their writing (of the 'for your kind attention' variety). I specifically liked the chapters on the use and abuse of the words 'also', 'both' and 'only', but the overall tone that drips with needless acid grates on you after a while. It may start off as mildly humorous, sort of like the ravings of a pointless uncle, but as I said, really grates after a couple of chapters. So much so that you begin to nitpick the author's writing style purely out of spite. (Who the heck uses the word 'whirligig' in a serious publication? Ha, take that, author!) Summary: the content's interesting but the delivery reaches towards the obnoxious. YMMV.
