So J.J. Abrams' 'Stranger' Trailer was for...

A whole 24 hours after J.J. Abrams' production company, Bad Robot, released a teaser for his intriguing upcoming project, called Stranger, the mystery has been unveiled (kind of): according to Bleeding Cool, the trailer was for the Lost creator's new book, which he is developing with writer Doug Dorst. The novel, titled S., is set to be released in October.

Bleeding Cool discovered that the Stranger trailer contains the same font as a postcard released by the book's publishers at an event promoting S. back in May. As any Abrams fan would expect, few details have been revealed about the book's plot, but it's known that its story will be told in a "Mystery Box" type way, meaning it will contain "20 to 22 pieces of ephemera in the 'real world'", according to Abrams' editor, Joshua Kendell.

If the Stranger teaser was meant to promote S., then at least some information can be gathered. It looks like water will play a large factor in the book, as well as the concept of identity. The trailer's voice-over spoke of "rebirth," and contained the statement, "what begins at the water shall end there, and what ends there, shall once more begin." It also showed an image of a man with his mouth sewn shut.

S., to be published by Little, Brown, will be released on October 29. So, that's good news for Abrams fans anxious with anticipation — only a little over two months before the full mystery will be unveiled.
