Are the settings you use real places?
Unless there’s a note in the book saying the area or town is made up, it’s real or at least based on a real place. The international locales in the Bad Boys Undercover series are all real. For example, for information on Pakistan for Falling Hard, I depended on blogs and videos from Himalayan climbers for visual guidance. For the Dirty series I did a lot of research on Germany, Morocco, Ceuta (Spain) and the Svalbard Seed Vault the Doomsday Vault).
