This one off novel was a collaboration between Neil Gaiman and Terry Pratchett before Pratchett’s death, and showcases well the talents of both authors. From Gaiman, we get some of the darker tones while Pratchett provides a nice sense of whimsy and humor.
The story is largely the same in both the novel and Amazon miniseries; Aziraphale and Crowley, and angel and a demon respectively, are on earth since the beginning of time, and watch as Adam and Eve leave the Garden of Eden. Now, in modern days, they are tasked with seeing that the antichrist, and then Armageddon, come to pass. In a twist no one foresaw, however, they are both friends and also actually enjoy living and doing human things. The rest of the novel follows them as they try to avert the end of days, while the opposing forces of Heaven, Hell, and Humans work to see it pass.
The TV adaptation on Amazon is an amazing piece of work, that keeps a lot to the original texts, although modernizing it a bit. The actors portraying Aziraphale and Crowley have amazing chemistry and provide very good entertainment. Although the series is rather short, it is quite worth a watch.
The novel starts out a bit slow for me, and reads too much like Gaiman, who’s writing tends to be a bit on the drabber side for my liking, but if you enjoy his other novels, this one is a must read.
