That cryptic J.J. Abrams trailer is probably for a book written by somebody else
Yesterday, J.J. Abrams’ Bad Robot released a trailer entitled “Stranger,” specifically designed to incite wild speculation about what exactly it portends. As expected, predictions ran rampant, from Lost spinoffs, to a video game project related to Bad Robot's partnership with Valve, to the last Rod Serling script Bad Robot acquired. But there's another project out there that currently seems the most plausible.
Bleeding Cool started piecing together information about various Bad Robot projects and stumbled across S., a novel due in October from Mulholland Books. It’s a story "conceived of and developed by"Abrams, but actually written by author Doug Dorst, a graduate of the Iowa Writers’ Workshop and former Stegner Fellow at Stanford. The first promo material for the book appears to be a postcard from Brazil, which you can see at The Huffington Post, that features copy written in the same font that appears in the “Stranger” trailer.
