Ellery's TBR clean up

You can start and finish this challenge whenever you like!

Since my TBR gains new additions faster than I can read, I've decided to challenge myself this year, and clean house a bit. Here be a list of about 100 prompts, which I will strive to complete by reading only books already in my TBR. I'm not putting an end date, because that will only add unnecessary pressure to the whole story.
Anyone is welcome to use this list, if they like.

Challenge prompts

1. A book set in a school

2. A book set in Scotland

3. A book published by Harper-Collins

4. A book featuring an aromantic or asexual character

5. Title starts with the letter "D"

6. There be dragons

7. Or vampires of the non-sparkling variety

8. A book by Agatha Christie (or Mary Westmacott)

9. A book by a Japanese author

10. A book with a flavour in the title
