Drop Dead, Fred

Xaviera Monroe used to have a fairly normal life. She would wake up every morning and get ready for work. Getting home from work, Xaviera would watch movies and read a book with her cat. She would occasionally go out to a club. She loved her life. Xaviera was a Hufflepuff at Hogwarts School of Witchcraft and Wizardry. After the war--she didn't entirely give up magic but moved to a muggle town and worked a muggle job.
Until one day...she woke up dead.

Here is where she meets a boy she really should have known. After all, everyone else knew him. They mourned his death and it really was very odd that Xaviera did not know who he was.

Fred Weasley was given the very specific job of watching her, getting to know her and knowing everything about her and her life down to the very littlest detail. Which is why it is his job to guide her in death.
