Last month, J.J. Abrams and Bad Robot released a mysterious trailer entitled Stranger, although it wasn't known if this was for an upcoming movie, TV project, or something else entirely. The next day, we reported that the video is actually for a new book entitled S. from J.J. Abrams and author Doug Dorst, which has now been confirmed by a second trailer and the website Take a look at this latest footage, then read on for more details about this novel, debuting on October 29.

Here's the official description of the book from its Amazon page, where you can also pre-order a copy of the novel.

"One book. Two readers. A world of mystery, menace, and desire.

A young woman picks up a book left behind by a stranger. Inside it are his margin notes, which reveal a reader entranced by the story and by its mysterious author. She responds with notes of her own, leaving the book for the stranger, and so begins an unlikely conversation that plunges them both into the unknown.

The book: Ship of Theseus, the final novel by a prolific but enigmatic writer named V.M. Straka, in which a man with no past is shanghaied onto a strange ship with a monstrous crew and launched onto a disorienting and perilous journey.

The writer: Straka, the incendiary and secretive subject of one of the world's greatest mysteries, a revolutionary about whom the world knows nothing apart from the words he wrote and the rumors that swirl around him.

The readers: Jennifer and Eric, a college senior and a disgraced grad student, both facing crucial decisions about who they are, who they might become, and how much they're willing to trust another person with their passions, hurts, and fears.

S., conceived by filmmaker J.J. Abrams and written by award-winning novelist Doug Dorst, is the chronicle of two readers finding each other in the margins of a book and enmeshing themselves in a deadly struggle between forces they don't understand, and it is also Abrams and Dorst's love letter to the written word."

The book will also include other materials between the pages such as newspaper clippings and a hand-drawn map on a napkin. The book will be shrinkwrapped so this extra content does not fall out. Here's what J.J. Abrams himself had to say about the story.

"It is difficult to describe because while it is a compelling mystery and love story, it is also much more than that. The work that everyone has done on S. is unlike anything I've ever seen. Frankly, I'm amazed it was even possible to do this project at all."
