Finding Serenity: Anti-heroes, Lost Shepherds and Space Hookers in Joss Whedon's Firefly is a compilation of essays edited by Jane Espenson with Glenn Yeffeth.

Due to Firefly's early demise it left viewers with unanswered questions and a certain sense of loss.

The essays attempt to resolve the unanswered questions brought up in the show, ranging from the origin of the Reavers, the multi-racial casting, and the use of the Chinese language.

Some essays are existentialist, seeking to define what freedom meant for each member of the crew, a theme that Joss Whedon seemed to be exploring.

It was followed by Serenity Found: More Unauthorized Essays on Joss Whedon's Firefly Universe in November 2007 by the same editor, including contributions by actor Nathan Fillion (Malcolm Reynolds in the series) and science-fiction author Orson Scott Card.
