Considering that IT and a number of other lengthy Stephen King novels have an audiobook edition, it's surprising that an audiobook version of The Stand has not yet been made available. Thankfully, Random House is planning a release for early next year:
"Random House Audio will be releasing the long-awaited unedited audiobook edition of The Stand which will be read by Grover Gardner. The exact date of publication has not yet been determined, but is tentatively scheduled to be on February 14, 2012. The recording will be released for purchase digitally by Audible.com and iTunes and available in the library market on CD."
Synopsis: One man escapes from a biological weapon facility after an accident, carrying with him the deadly virus known as Captain Tripps, a rapidly mutating flu that - in the ensuing weeks - wipes out most of the world's population. In the aftermath, survivors choose between following an elderly black woman to Boulder or the dark man, Randall Flagg, who has set up his command post in Las Vegas. The two factions prepare for a confrontation between the forces of good and evil.
