River of Teeth

The concept is so unique and bizarre — I wonder if it was inspired by real animals or entirely fictional. How did the author decide to make them central to the story?

The humor lightened some of the darker moments, but I still felt the stakes were high. Was that contrast intentional to reflect the characters' complexity?

The world-building felt so detailed and immersive. I’m curious whether the setting evolved naturally or was carefully planned from the beginning.
