Book: Advent also means “second coming”: Read a pastiche, or a book written by an “authorised author” by the deceased author’s estate. OR: There are four Sundays in Advent. Read the fourth book of a series or a book with the word “four” in the title.
I didn't end up reading a book that fit this, so I'm using the joker card to claim it with Becoming instead.
Edited to unclaim due to incorrect Joker Card usage. Whoops!
