Consider this mix: several hours with Narendra Modi, pumped-up ego and new swagger after victory; another several hours with handpicked associates; detailed access to movers and shakers of the Modi campaign and (as reported) a couple of volunteers from the campaign hired as researchers for the book.

But first, one question: should all narratives, despite being breezy, with an engaging style, be considered book material, or should it remain long-form journalism?
