Just a bunch of prompts related to mystery or thriller books. 
It last 14 months because I read slowly. You don't need to complete all of them, DNFs are acceptable and respectable in this challenge. 
I encourage you to read more diversely, adding BIPOC, LGBTQ+, and non-western-centered authors. Remember to put your money where your mouth is (or something like that). 
Double up is allowed.
But overall, enjoy what you read all the time.
The comments behind the promts are jokes about these tropes. Not to be taken seriously.
