THE PICKLE INDEX  tells the tale of an incompetent circus troupe that sets out to rescue its ringmaster, Zloty Kornblatt, from a dystopian, brine-obsessed government. If that doesn’t pique your interest, maybe this will: The Pickle Index is a paperback. But it’s also a beautifully illustrated, hardcover set of two volumes that tell the story in tandem. Oh, and it’s also an app. Not an e-book, mind you—an app, where a user’s “Citizenship Quotient” points are allocated based on how often you upload actual pickle recipes. Confused? Good. That’s kind of the point.

The fact is, The Pickle Index is not a traditional novel, nor is it a conventional app. When Eli Horowitz and Russell Quinn set out to create the multimedia storytelling experience, they made a conscious decision to eschew hallmarks of design like accessibility and ease of use. Instead, they provide multiple entry-points into an intricate and immersive world. In doing so, they’ve reimagined what a digital literary experience can be.
