Soul music, paperback/terry pratchett

The sixteenth Discworld novel.

 Theres no getting away from it.

From whichever angle, death is a horrible, inescapable business.

But someones got to do it.

So if Death decides to take a well-earned moment to uncover the meaning of life and discover himself in the process, then there is going to be a void of specific dimensions that needs to be occupied, particularly so when there is trouble brewing in Discworld.

There arent too many who are qualified to fill Deaths footsteps and it certainly doesnt help the imminent cataclysm that the one person poised between the mortal and the immortal is only sixteen years old.
