Arcadia by Iain Pears is the name of a novel, as well as an app. While it's by no means uncommon to find books that have been enhanced with digital applications, Arcadia sets itself apart as Pears created it as "a novel conceived and written for an app."
Arcadia is set up with ten characters across three worlds, creating hundreds of possible paths for readers to explore in their own way.
Through the form of an app, Arcadia by Iain Pears is able to approach an entirely new way to telling stories in a way that books and ebooks are unable to. With Arcadia, Pears describes: "I wanted to do something new. I wanted to give you the freedom to put the tale together in your own way."
