This book is probably the best thing Pratchett has done since Mort. The storyline is brilliant, with an interesting mix of characters. Basically, it tells of the events of the Last Days, and how Crowley, a jaded demon, Aziraphale, a book-collecting angel, a middle-aged medium called Madame Tracy, Newton Pulsifer (pvt., Witchfinder Army) and Anathema Device, a young woman who is more psychic than can possibly be good for her, must work to save the world from Heaven, Hell, the Four Bikers of the Apocalypse, the Other Four Bikers of the Apocalypse, and an eleven-year-old Antichrist with an overactive imagination.
The writing is hilarious throughout, and the entire story makes you want to laugh, cry, and break out the holy water just in case...

An excellent book about Armageddon "ala Hitchiker's Guide". The story is based on an angel, Aziraphale, and a demon, Crowley, who have come to a kind of earthbound truce from spending more time with each other than their allies. The angel and devil are working more or less together to thwart the latest plan of the powers-that-be... Namely, the Anti-christ is loose in the world, and unless they find him soon, there won't be a world left to save.

Overall, I thought this book was excellent. It moved along at a pleasant clip and never ceased to be amusing and humorous. A nice piece of light reading, a must read for anyone who likes Douglas Adams...
