The mysterious S. videos continue! Though, this clip is more straightforward than the last. Have you picked up a copy of Doug Dorst & J.J. Abrams’ novel S.? If not, now’s the time to jump in. In addition to briefly discussing the inspiration behind their book, in the video embedded above Dorst and Abrams explain that they’ve signed five copies and have hidden them in five different cities around the nation. They dare you to find one, read it, and then ditch it for someone else to discover (or keep it, that’s entirely up to you). Does this concept sound familiar? It should: D&A are borrowing the “Send Wonder” concept imagined by artist/magician Jamie D. Grant; he previously collaborated with Abrams’ Bad Robot and magic destination Theory 11 to create the Mystery Bottle. Grant’s “Send Wonder” campaign is all about spreading inspiration with the world through sharing and random discovery. Want to be one of the lucky five to score a signed copy of S.? Follow Dorst on Twitter where the author will be dropping clues to their whereabouts; first stop: NYC.
