The list author says: "If you're a Pratchett fan, you probably have trouble finding out which books your favorite character(s) are in. No worries! This is a list of books with Susan, DEATH's granddaughter, in them. If you haven't read Terry Pratchett, any of these are a good place to start! More lists coming soon!"
"Ho-Ho-Ho...Oh, No, no, oh! The unusually human discworld version of DEATH must deliver toys to all the children on the disc, while Susan, with the help of UU wizards and the oh-god of drunkness must track down an assassin."
"Susan's just lost her parents - and realized that she's the adopted grandaughter of DEATH and has some of his powers (genetics are funny in Discworld). Mourning the loss of his adopted daughter, DEATH stops doing his job and Susan takes over. It's not too bad until she must come for a handsome young musician who's introduced 'music with rocks in' to Discworld."
"So Susan has absolutely no part in this book BUT we meet her parents and see them fall in love. We also get insight into Sould Music There is I think a Discworld Big Comic or graphic novel of Mort as well"
