Bound, the app the Exiles will use for its narrative, has soft-launched in the US and Canada, and even though the Exiles material isn't released yet, it does come with exclusive content from Neal Stephenson, a bona fide sci-fi legend.

The serial is the first full-fledged feature for Bound, which aims to combine prose, art and audio with community features in geeky genres ranging from sci-fi and fantasy to thrillers.
