The book is voluminous and informative. It almost covers everything related to Indian National Movement. The narration is almost is on the lines of Rankean history to some degree. author though sounds biased towards Indian National Congress in certain aspects but then that possibly isn't a flaw.
at times the author paraphrases the same point multiple times in continuous paragraphs, but then no complaints since it helps you reread and correctly understand the point author is trying to convey to the reader.
In the midway I realized that it is truly a pro-congress or pro-nationalist book. But, then also I proceeded. There are times, when it tries to justify the stand of Congress on critical matters. A reader must read it with this 'bias' in mind of authors because as already been said by others that most of the authors are from JNU and in some way or other are associated with different government institutions.
However, it is a good read in terms of it's style of presenting history. In fact, one can easily find that history is not merely about memorizing the dates, it is more about seeing the undercurrent of thoughts which were determinant in making that date historical.
All in all, a good read but needs patience...
