Aguas oscuras (Kate Linville & Caleb Hale 5)

The atmospheric backdrop adds so much to the suspense, but I wonder if the author based it on a real place or created it from imagination.

I found myself getting impatient during some sections, but I also see how it might serve the story's emotional depth. Was that intentional?

The characters felt fully realized even as the story kept me guessing. I'm curious about the craft behind maintaining that balance.
