She also appears in "The Books of Magic" (first volume, 1991, also written by Gaiman) at the very end of time, where her function is to set things in order and close the universe down. She meets Timothy Hunter and Mister E there after Mister E has taken Timothy all the way to the end of time, because only there can he kill Timothy without fear of interference. Death stops the murder on the grounds that "I took both of you billions of years ago." She sends Timothy back home, but forces Mister E to return the hard way. John Ney Rieber included her in "The Books of Magic" (vol. 2 #3-4), in which she lets Timothy Hunter hang out at her house and hold her teddy bear, Cavendish, while he is recovering from the venom of the Manticore. Hunter later encounters Death walking in the rain in "The Books of Magic" #25, and there was later an arc about her in "". In "Hellblazer" #120, Death appears briefly in a pub filled with ghosts.
