The preeminent source for ''Lost ''fans, this fourth volume of the popular companion series finds the show having regained both audience fervor and critical praise as the rescued ''Oceanic 6'' decide whether or not to return to the island for those left behind. Featuring the most comprehensive episode guide available as well as many never-before-seen photos, this resource is invaluable for all followers of ''Lost,'' whether casual viewers or hard-core theorists. With an analysis of how John Locke could become the mysterious Jeremy Bentham, the in-depth handbook also includes background information on the show's historical, philosophical, religious, and literary references, such as those alluding to James Joyce's ''Ulysses ''and Stephen King's ''The Stand.''
