S. (Dorst novel)
S. is a 2013 novel written by Doug Dorst and conceived by J.J. Abrams. The novel is unusual in its format, presented as a story within a story. It is composed of the novel Ship of Theseus by a fictional author, and hand-written notes filling the book's margins as a dialogue between two college students hoping to uncover the author's mysterious identity and the novel's secret plus loose supplementary materials tucked in between pages.
S. has been called "part work of art, literary experiment, and love letter to the physical expression of books."
