Kobo has created an augmented reality game to promote eReading. The game is called The Descent and is inspired by Dante’s Inferno, Dan Brown’s upcoming book Inferno and the works of the self-published author J.F. Penn, which are themed around Dante’s Inferno and the nine circles of hell. The promotion encourages readers to download and read two free eBooks by Penn – Sins of Temptation and Sins of Violence (both of which are Kobo exclusives)– in order to look for clues to crack the code of the online game. The author’s third book in the series, Sins of Treachery, comes out in September.
