A very interesting aspect to the book is the presence of a chapter (about a girl's diary) set in a particular form, which has probably never been used in a mainstream literary novel. Some critics think of it as a gimmick, while others have lauded the idea. Egan says she first thought of it from how the 2008 Obama campaign benefited from one such document to spur a turnaround in their fortunes.
What form is this chapter in?
