I thought it was written by James Rollins or someone like that. I remember it’s some sort of adventure thriller book and believe it was part of a series.

Michael, around what year did you read this book?

Who are the main characters? What are they jobs?

Story's time period and location/ country?

I read it within the past 5 years but don’t remember how old it was when I read it. I don’t recall main characters specifically but they were some sort of elite quasi-secret agent group. Story was set present day. I can’t remember a location.
