Hershel and the Hanukkah Goblins by Eric Kimmel (a book set around a holiday other than Christmas)
Hershel is a traveler coming into a small town at Hanukkah-time. Unfortunately, the town is plagued by Hanukkah-hating goblins! A lovely little story about Hershel's fight for his holiday.
The Autobiography of Miss Jane Pittmann by Ernest J. Gaines (a book that takes place over a character's life span)
The fictional autobiography of a black woman who lived from the abolition of slavery all the way to the Civil Rights movement.
At Bertram's Hotel by Agatha Christie (a book set in a hotel)
Not one of Christie's best, in my opinion. I feel like she took a large, complicated topic and told about it in too few pages. The antagonistic force was never fully explained.
Also read, but not for the challenge:
Six of Crows by Leigh Bardugo
What If? Serious Scientific Answers to Absurd Hypothetic Questions by Randall Munroe
