Not just this, if one goes to Modi's website, many e-books like "Convenient Action" have been written by him and a few like "Narkesri-Narendra Modi", a Gujarati translation of a Kannada book penned by a young writer.
According to Westland publications managing editor Sudha Sadanand, Mukhopadhyay's book had done extremely well even when Modi was not declared a prime ministerial candidate. The book was released in 2013.
"The book had evoked great curiosity as we were the first amongst several others to have a book on him. It has now gone into a reprint and with elections around the corner, the demand is bound to increase manifold," she added.
Nag's book too has been well received, said Kapil Kapoor, director of Roli Books, adding they are expecting a spike in sales if the BJP wins and comes to power.
This isn't the end. A few publication houses are in the process of releasing books on Modi in May and more will soon follow.
The Modi clout will just grow bigger.
