This readathon, aka Whodunitathon, is a month-long challenge where you choose prompts to create a murder mystery plot of your own. There are two paths you can choose from - this one, the Novella Track, requires you to read 3 books. The Novel Track, which requires 13+ books, has a separate StoryGraph challenge.
