Hana - Lauren Oliver This short ebook story is a companion to Lauren Oliver's novel, "Delirium," telling a part of the story from the viewpoint of Hana, Lena's best friend. Although it's mildly entertaining to re-read the story from a new perspective this story relies on a knowledge of the original novel, and doesn't add a whole lot of new information, either -- with the exception of the final sentence -- so it's neither a stand-alone story nor a continuation nor an addition... just kind of a redo, and not particularly necessary, in my opinion.
