L'ultima sentinella

The story moves at a breakneck speed, and I'm curious whether this was a conscious choice or evolved naturally during writing. Did the pacing help build the tension more effectively?

Jack Reacher's unwavering commitment to justice made me root for him, but at times I wondered if his choices also raised difficult ethical questions. What did others think about his sense of morality?

The setting felt so integral to the plot and atmosphere. I'm curious whether Lee Child based it on a real place or if it was crafted to serve the story's tension.
