Of the 1,624 I tagged as Read:

Lowest: Passenger to Frankfurt by Agatha Christie - 2.88 stars based on 11,556 ratings. It’s definitely among her worst novels, but I’m surprised it’s so much lower than some others. I think Man in the Brown Suit is much worse and it has a 3.95.

Highest: The Divide: A Brief Guide to Global Inequality and Its Solutions by Jason Hickel - 4.63 stars based on 2,248 ratings.
