It begins with pain, piercings and blood. The book is read in installments of just a few lines in each status update from “Zwirbler” its protagonist, but other Facebook junkies can twist the plot as they desire, or simply comment on the writing or events. The result is at times poetic and painful. Contributors continue a line of thought, description or send the story in a completely different direction. Or they give advice. Interactive novels are all over the internet, but 40-year-old author Gergely Teglasy (or “TG,” as he calls himself) claims his is the first on Facebook. He launched his novel in German for people over the age of 17 at the beginning of this month and, since then, over 3,000 people have “liked” it on the social media site. Fans can also subscribe to a podcast of weekly novel episodes. He adds a “Zwirbler” status update, or new chapter, to the Facebook page often enough to keep readers interested, but consciously tries to avoid clogging their news feed. Teglasy pointed out that while in the past few decades the internet had changed the way people read, that didn’t mean it was restricting. On the contrary, he said that Facebook could enrich the experience with literature by prompting people to keep reading.
