The book is interesting in parts, and the reason for that is either the editor or the author.
Tamal's writing makes for easy reading. He starts off with a chapter on what happens when Bandhan becomes a bank. He then moves back to the origin of the idea of Bandhan, and even before that. My issue with the book was the constant back and forth across timelines in each chapter, as well sometimes within a page.
Not sure what purpose is achieved by say an event in 2009, followed by an event in 2012, and then writing "before all of that" and going back to 2002 - all within a space of one or two pages. The years are just examples, I have not gone back to check out the exact years mentioned in the book.
The other issue I have with Tamal/editor is the inconsistency in the use of the numbering system throughout the entire book. This seems to be a problem with many of our financial newspapers too. Either it is fashionable to them to mix millions with crores, or plain laziness, not to stick to either the Indian numbering system or the American one. Also, I wonder how many pages could have been saved if the data about which MFI was funded when and by whom was presented in tabular format, instead of it being put down in paragraph form. If the idea of a table in a book like this was not acceptable to the author, editor or publisher, perhaps, they could have avoided the level of detail on the numbers too.
The book is most interesting from Chapter 7 - On the Way to Becoming a Bank onwards. Personally, I found the Appendix the most interesting, as well as the chapters on Vijay Mahajan & Vikram Akula.
