Death goes on vacation and decides to hire an assistant to handle the job of collecting souls while he's gone.
Terry Pratchett's novels are some of the funniest writings I've ever come across. He has been one of my favorite authors for most of my life! :) "Mort" is one of my favorite books in Pratchett's magical 'Discworld.' Everything about Death and his white horse ''Binky'' is fascinating, engaging, and there's never a dull moment.
I would strongly suggest any of Terry Pratchett's Discworld books. :) The funniest, most well written works!
