Named HarperXXI, the titles are from a range of genres from poetry to graphic novel, crime to romance, sport to fitness and business to cinema.
"We're releasing 21 e-singles made up of exclusive new content from our popular writers. They're short, snappy 21 minute reads each one available at the pocket friendly price of Rs. 21," the publishing house said.
The titles can be downloaded from Amazon India as Kindle e-readers for Rs 21.
"We are hoping that Harper XXI will help us reach new and younger readers and ease people into the idea of reading digitally which is clearly the way forward," says V K Karthika, publisher and chief editor of HarperCollins India.
Two of the top books on offer are late Sunil Gangopadhyay's "Neera" (translated by Arunava Sinha) and a take on Bollywood film "Gangs of Wasseypur" by Jigna Kothari and Supriya Madangarli.
Throughout his writing life, Gangopadhyay wrote a continuous sequence of love poems addressed to a mythical woman named Neera. These poems became the mantra of two generations of young women and men.
From ardent, sexually charged verses of early infatuation, through the demanding and sensual rhythms of a full-blown relationship, to the mellowing middle-age memories of romance, the Neera poems are a pulsating testimony to the cycle of passion, desire, and, inevitably, unrequited longing.
This is a selection of the most stunning of Gangopadhyay's Neera poems, most of them translated for the first time, and as capable as ever of sparking off a hundred love affairs when recited aloud.
Running close to five hours and 30 minutes, and boasting of no big stars, "Gangs of Wasseypur" is unlike any Hindi film that came before. One of the most feted Indian films of recent times in international circles, it has been spoken of as India's answer to "The Godfather".
Supriya and Jigna go behind the scenes through the film's chaotic gestation to bring to life the trials and tribulations, the triumphs and ecstasies involved in its making.
