Amazon Studios will adapt Neil Gaiman and Terry Pratchett’s novel “Good Omens” into a six-episode limited series, the studio announced on Thursday.

The 2006 novel takes place in 2018 when the Apocalypse is near and Final Judgment is set to descend upon humanity.

Set to debut in 2018 on Prime Video, “Good Omens” will consist of six one-hour episodes entirely written by Gaiman, who will also serve as showrunner. (Veteran fantasy writer Pratchett died in March 2015.)

This marks the latest Gaiman novel to get turned into a TV series. Starz will premiere its adaptation of the best-selling author’s “American Gods” later this year. In addition, “Hamilton” producer Jeffrey Seller and his producing partner Flody Suarez are producing an adaptation of Gaiman’s “Interworld” for Universal Cable Productions.

According to The Nice and Accurate Prophecies of Agnes Nutter Witch — the world’s only completely accurate book of prophecies, within the universe of “Good Omens” — the world will end on a Saturday. Next Saturday, in fact. Just before dinner.

So the armies of Good and Evil are amassing, Atlantis is rising, and tempers are flaring. Everything appears to be going according to Divine Plan. Except Aziraphale, a somewhat fussy angel, and Crowley, a fast-living demon–both of whom have lived amongst Earth’s mortals since The Beginning and have grown rather fond of the lifestyle–are not actually looking forward to the coming war. And someone seems to have misplaced the Antichrist.

BBC Studios is co-producing the new series with Narrativia and The Blank Corporation and in association with BBC Worldwide for Amazon Prime Video and the BBC.

Along with Gaiman, Caroline Skinner and Chris Sussman will executive produce for BBC Studios; Rob Wilkins and Rod Brown will executive produce for Narrativia.
