Interactive fiction is nothing new — we've had it since Choose Your Own Adventure books rolled out. But an ebook available now for the iPhone and iPad is taking interaction to a new level: Readers have to travel to specific locations to unlock portions of the story.
The Silent History is divided into two parts: Testimonials and field reports. The testimonials, which are divided into six volumes of 20 chapters each, are automatically unlocked as the story unfolds each day. But the field reports require an unprecedented level of interaction: They can only be read by traveling to specific locations, and readers are encouraged to write and contribute their own localized installments.
Call it gimmick marketing or innovative storytelling, but one thing is for certain: people are talking about The Silent History, and some early readers are already addicted to the chase. The Week has more about how the book works, and how people are already changing the story's narrative. Link
