Outlaws of the Marsh

The novel has a vast cast, and I’m curious how the author chose whose perspectives to develop more deeply. Was it based on historical importance or narrative flow?

Reading about outlaws fighting against corrupt authorities made me think about modern notions of justice. Do others see parallels or differences in how rebellion is portrayed?

The world-building is so immersive, from customs to social hierarchy. I wonder if this was drawn from personal knowledge or extensive research.
