Super long time since I read it, but there was a kids book I read that was all dialogue (excellent for the audiobook). It was about a kid in the 40s/50s who loved listening to the Lone Ranger and other radio shows. It translated perfectly for audiobooks

I think it was “Who was that masked man anyway?” By Avi. He has a lot of unique kids books iirc

I think I read the last HP book in less than 12 hours when I was a in middle school.

I also read 2 Redwall books in a single night when I was 11

I think that’s why I loved Artemis fowl as a kid. A lot of the wcience was made up, but it made me think being really intelligent could be useful in dangerous situations, and was useful past school
