Abrams discusses his new project, an interactive novel entitled S, in which two readers leave notes for each other in the margins in this interview for PBS.
So what occurred to me was what would happen if someone found a book and there was a bunch of writing in it, and the person read some of the book and read some of the notes and, almost as a joke, wrote some notes in response, and then left the book back for the person. What if that person who originally wrote the notes found the book, saw those notes, and actually left a thing? What if a relationship began between two people through a book? What if a book became a means to communicate?
