Operation Amazonas

The detailed descriptions made the setting come alive, but I'm curious whether the author has personal experience or did extensive research to craft such an authentic environment.

The story built suspense well, but the conclusion felt a bit rushed. Was that intentional to heighten the tension or just a writing choice?

Sometimes the plot leaned heavily into action, but other times the clues and puzzles took center stage. Did anyone find one aspect more compelling than the other?
