Funny.

Right off the bat, a humorous look at the apocalypse that totally delivers on the laughs. Not that I've read any Terry Pratchett yet, but a recommended read for his, and Gaiman's, fans. And both authors write in each other's style so well, you hardly know you're reading a collaboration. It feels like a novel from one author. And as someone who has read no Pratchett and a lot of Gaiman, I cannot tell what part is written by what author. Very well done.
