Derrial Book is a fictional character played by Ron Glass in the science-fiction/Western television series Firefly and its sequel movie, Serenity. He is a Shepherd — a kind of holy man or preacher — and provides frequent spiritual advice and perspectives for the crew of Serenity.

He is almost always referred to as "Shepherd Book", presumably an indicator of his status as a respected religious figure. Book is a Christian of an unknown and probably fictional denomination. Throughout the series, he makes references to Christian theology and consults the Bible.

In the comic Serenity: Those Left Behind, Book expresses concern that he is being corrupted by living on Serenity and he leaves the ship. By the time Serenity begins, he has moved off the ship to the planet Haven. In the film, Book is killed by an Alliance soldier sent to destory Havenafter Serenity manages to shake an Alliance assassin known only as "The Operative". However, he was not a passive figure in the events leading up to his death; he defended Haven and "killed the ship that killed them".

One of the most debated aspects of the show is Shepherd Book's secret past. He holds some sort of priority status within the Alliance (see below), and on numerous occasions has demonstrated a depth of knowledge in a number of fields, including space travel, firearms, hand to hand combat, and criminal activity.

In the fourteenth and final episode of Firefly, "Objects in Space", Simon berates the bounty hunter Jubal Early for assaulting Book, a Shepherd. Early only replies mysteriously, "That ain't a Shepherd." Early's implication that he knows something about Book's history is never explained. In the DVD commentary for the same episode, Firefly creator Joss Whedon comments that Early's methods for dealing with each crew member are custom-tailored to their personalities. Early disposes of Mal in a straight-forward manner; Joss then notes that Early's method for taking out Book is equally straight-forward, alluding to a similarity between the two otherwise different characters. Earlier in the episode, a similarly inscrutable insight occurs when River Tam accidentally reads Book's thought: "I don't give half a hump if you're innocent or not! So where does that put you?"

Another hint to Book's mysterious past is shown in the episode "Safe". In it, Book is accidentally wounded. Simon, the ship's doctor, had been kidnapped by locals, and with Book's condition worsening, Mal is forced to seek help from an Alliance cruiser. The commanding officer, after tersely dismissing Mal, changes his attitude once one of his officers shows him Book's identity card, and though the exact information on the card is never shown, the crew does note that it affords Book access to the medical facilities on board. The only other identitiy card apearing in the series belongs to the Alliance mole and is used during his attempt to sign on to the Cortext, which may be a sign of past Alliance ties. After seeing the information on Book's card the commander immediately halts his admonishing of the Serenity crew. Upon return, Book states "It is good to be home."

Though Book himself often hints at a dark past, he refuses to discuss it openly. When asked by Mal if he would like to explain the preferential treatment the Alliance gives him in "Safe", he responds, "I surely would, and maybe someday I will." However, in Serenity, Book seems more reticent to share. After Book describes the methods and mentality of an operative of the Parliament, Mal presses him for some explanation of his knowledge, but receives none:

Mal: It's of interest to me how much you seem to know about that world.

Book: Wasn't born a Shepherd, Mal.

Mal: You have to tell me about that someday.

Book: No, I don't.

The truth about Book's past may never be known, as Book perishes in Serenity, without ever revealing his secret. However, on 22 April 2006, Firefly/Serenity star Summer Glau (River Tam) stated at the Supanova 2006 convention held in Brisbane, Australia, that she was aware of the "secret" of Shepherd Book.^{[citation needed]}

The novelization of Serenity details the Operative's assault on Haven. During this time, Book shoots down an Alliance cruiser and the Operative disables him and orders Alliance soldiers to shoot him. There is a brief monologue which hints that the Operative knows something about Book that Mal and his crew do not. The Operative states that Haven is the last place he would've expected to find Book, and that his Shepherd's clothing is the last thing he would've expected Book to be wearing, based on what he's read.

During production of the film Serenity, Book's first name was Meria, and it appears as such in the documentary "Re-Lighting the Firefly". However, by the time the film was completed, Joss Whedon changed his first name to Derrial, which is the way it appears in all printed official works based on Firefly, (including the role playing game, the novelization, and the two Official Companion books written by Whedon. ) and Derrial is the name featured on his memorial in the film Serenity.
