Last month when J.J. Abrams dropped a trailer for his mysterious new project, few probably expected it to be a book. Another trailer was released yesterday and in true Abrams fashion it reveals little as to what it’s actually about. Except that S. is, in fact, a book. The work is a collaboration between Abrams who developed the concept and writer Doug Dorst who penned it. S. will be available October 29th. Check out the new trailer below.
