Nothing to See Here has very few characters and a very good narrator!

I listened to Someday I Shall Astonish the world by Nina Stibbe on audio and enjoyed it. It’s about two friends and easy to follow, light but not dumb. I like her books. Quirky, British, funny, heartwarming.

Yellowface by RF Kuang

The audiobook for All The King's Men is excellent. I think the characters are distinct enough that the number of characters won't be hard to follow.

Me Before You by Jojo Moyes doesn't have a lot of characters.

Books by Nicholas Sparks generally don't have a lot of characters. He writes romance novels.
One of his books is called Nights in Rodanthe. It is about a man and a woman who shelter from a storm together. There are very few characters in that book.

The Four Winds by Kristen Hannah comes to mind.
There are not a lot of characters, and you will learn all about the dust bowl.
But it is sad from beginning to end.

Looked for older ones in my Audible account - Heart's Invisible Furies, Trevor Noah's Born a Crime, A Man Called Ove are all older ones that I really liked on audiobook.

Fiction or non-fiction are both fine. Here’s what I’m seeking:

—not a new best seller, because I’m hoping for availability on Libby

—if fiction, an engaging story with just a few main characters. I find audiobooks with a ton of main characters too hard to follow. I like things that are interesting right from the start and books that inspire conversation. All genres are fine.

For nonfiction, I like gripping stories from which o learn something.

Ideas?!
